Black Diamond Hilight review

I’ve used the 2 person Hilight quite a bit in the last year, with performance quite as I expected it to be, perhaps one or two things surprising. This makes for something of a dull write up; it is a quality tent, well conceived, with defined limits. There a few things that could be done better, but so long as one chooses it wisely, the Hilight will make for a good shelter.

Dimensions are the first concern, and really the only area where I think Black Diamond went wrong in the design. 82 inches is simply too short for anyone of average (5’8″ or more) height. I fit in the Hilight, sleeping diagonally when using it as a solo tent, which is how I imagine 90+ of people use it. That is fine, but I think it would make more sense to stretch it a bit, while making it narrower, perhaps even symmetrical. Rather than being 82 inches long, 42 inches wide at the foot, and 50 inches wide at the head, give it the 87 inch length of the Eldorado, and a uniform 48, 46, or even 44 inch width. Two people are going to be in full bivy/alpine mode using the Hilight anyway, so going halfway to providing comfortable room doesn’t seem logical, when a longer and narrower footprint would only be better for both a duo and a soloist.

I’ve been quite pleased with the performance of the Hilight. Snowshedding is a natural strength of little wedge tents like this one, with the near vertical lower walls, and while I (somewhat annoyingly) avoided big snow storms on trips this past, modest snowfalls sluff off unnoticed. I anticipate performance in heavier snows to be more than acceptable. Performance in wind is a bigger question with wedge, and with the Hilight especially, given the wing pole over the doors. In sustained 30-40 mph winds the Hilight has proven very stable, especially when the side guy points are used. It is a very quiet tent under these conditions, with impressively little movement. I look forward to testing it, the wing pole especially, in harsher conditions, but realistically those don’t happen very often. I’d currently take the Hilight most anywhere, anytime in the mountains and be comfortable that with reasonable sight selection and prep I’d do fine.

Ventilation and condensation, and mild weather performance generally, has been an area of unexpected strength and satisfaction. Seeking ease of pitch and total bug protection I took the Hilight on a weeklong packraft trip down the Middle Fork of the Salmon, as well as on an early September elk hunting trip on the prairie badlands of eastern Montana. The former trip ended up being quite warm, somewhat rainy, and had a huge number of ticks. It was really nice to zip into my tent after an evening when I pulled half a dozen or more bloodsuckers off me, and nicer still to have good venting for a whole rainy evening and wake up with almost no condensation. The Middle Fork isn’t a humid environment, but on a permitted river tip one often camps out of necessity closer to the water than ideal moisture management would dictate, and in the Hilight this just wasn’t an issue, due to both the generous venting and the fabric. It was very warm on the elk hunt, and still buggy, which had me appreciating a full tent rather than a tarp, with a full panel of mesh I could leave open to the wind on nights that barely got into the 50s.

Because the venting is so effective, and because resewing and sealing will be a bit of a job, I have yet to get around to cutting the top tunnel vent out. I remain convinced the big, dual flaps make it redundant, but have yet to actually conduct that experiment. Even if I can drop 6 ounces from the canopy, the Hilight is never going to be the choice for truly light and fast trips, unless they involve multiple nights camped on deep snow. Being able to stomp a platform, then use your poles to anchor one side and your skis the other makes this type of tent the clear choice for deep snow camping and ski mountaineering. I would like the corner stake loops to be just a hair bigger. The 104mm wide tails of my spring skis just barely do not fit, though adding cord loops is no big deal.

The accessorizing of the Hilight is something I appreciated every time I used it this past year. As mentioned in the initial post, the stakes are excellent. It is nice to not have to replace, or augment, the stock stakes of a new $400 tent. The guyline is also high quality, and reflective, something I appreciated deeply on the second night of the elk hunt, when darkness and a final futile stalk caught me 3 miles from my tent on a very dark night. I had pitched it atop a knoll precisely to manage this eventuality, but with no moon each knob and ridge becomes like the others, and in my very tired state I was really psyched when my headlamp picked up glowing cord across the coulee, especially as my stash of food and water was inside. In gnarly conditions one could use more cord, but one might well go years with the stock amount being entirely adequate.

There are a lot of lighter, in some cases drastically lighter, double wall tents newly on the market which pencil out as functionally very close to the Hilight. For a lot of users those options, with less robust fabrics, fussier pitches, and worse weather resistance, are probably a better option. I just like the Hilight, added weight be damned, because it is both (surprisingly) versatile, and because it has every appearance of lasting a decade or more. Shelter options are interesting, but I don’t find them especially sexy, and having the Hilight available to tick every non-family tent box I require is both a practical and aesthetic virtue.

The death of Purple

I’ve cracked three nalgene bottles in the past two decades.  The first was a classic 1 liter in milky plastic, before lexan invaded REI and college lecture halls.  It was ancient and wrapped in duct tape, and split radially when I dropped it in the Sylvan Lake parking lot, which was sad.  I think I was relegated to old juice jugs for the rest of that summers rock bumming.  The second was a few years later, Elephant Butte in Arches, at the flat sandstone base of the exit rap.  I got lazy, it might have been the third lap that day and the 40th that year, and let a single kink in the opposite strand rise 30 feet in the air.  I spent 10 minutes trying to huck a partially full 48oz silo through that loop, tied to the other end, before it shattered into pieces striking the rock.  The third was just the other week, when I gave Purple a stout whack on a tree, to split loose the ice which had layered inside after a 10 degree evening.  Purple cracked, and functionally, was no more.

img_0753

We found Purple on this trip seven years ago, in the midst of the talus along the west side of Norris Mountain.  Purple has been around a lot, on my first successful elk hunt, most memorably.  And this is why I’ve always like nalgene bottles.  They aren’t invincible, but they’re close enough, in the face of accidents and hot water and intentional abuse, that over the years deep memories accumulate.  Purple has the sticker from our Double Duck, and the one from that place with best coffee porter, and the stack Jamie sent me after I proofed their gorgeous map.  I don’t quite have any ideas what I’ll do with it, but I’m certainly not ready to just put it in the trash.

Without Purple, we have perhaps nine or ten nalgenes in the house.  Some are hiding in dark corners.  A few sit in the mud room and are used daily.  I believe, years ago, I bought one of them.  Another was a gift.  Several more were freebz at trade shows.  The rest, a solid majority, were found in the wild, taken home, cleaned, sterilized, restickered as needed over time, and adopted.  And for the pleasure of keeping fewer gatorade or smartwater bottles out of the wild, I’ll gladly keep hauling the ounces.

Montane Allez Micro Hoodie review

Not necessarily a huge amount to say here: the Allez Micro is a hooded quarter zip baselayer shirt, made from Polartec High Efficiency, a fabric which was one of the very best innovations of the past decade.  I reviewed the Patagonia Capilene 4 hoody back in the day, when it was one of the very first pieces to use the fabric.  Later that year I bought a Capilene 4 long sleeved crew, and have used that since, when the weather gets reasonably chilly.  I ended up passing that gen 1 Cap 4 hoody along, mainly because the hood was too tight for all day comfort.  I’ve periodically missed the warmth and functionality of having a hood in that particular layer, as well as the versatility of being able to use a warmer baselayer hoody as a midlayer, too.  So I bought an Allez Micro, and have been happy.

img_0723

The main, perhaps only difference of substance between the Allez Micro and the current Patagonia Thermal Weight hoody is the hood, with the former being a single layer, and the later double.  I much prefer the reduced warmth, and enhanced moisture transport, of the single layer.  For the same reason, I much prefer no pockets on a shirt like this.  I did buy the Allez Micro in size large, which lets me wear it over a t-shirt if desires, while still being slim enough for layering.  This also makes the hood big enough to wear for days at a time, even over a variety of hats.  Sleeves and torso are very long, almost excessively so, though it makes the thumb loops fit ideally, and the fabric is light and flexible enough that some excess around the wrists goes unnoticed.

img_0722

Polartec HE was on the vanguard of the defining textile apparel trend of the past decade, and understanding how unusually, occasionally exceptionally wicking and air permeable fabrics interact as various parts of a layering apparatus.  The Allez Micro, for example, is light enough and would seem to be more than fast wicking enough to be a hot weather baselayer.  A few months ago I found myself wearing it on a windless day pushing into the 80s, even at 7000 feet, and having it rather than something like the Pulse hoody contributed significantly to my pace suffering in the heat.  Not only does the grid fabric trap air and as a result add warmth, when worn alone on a calm day, it also wicks too fast to work in hot weather, as the fabric effectively eliminates convective cooling.  That same attribute is of course it’s main virtue in the cold, and why most of the time Polartect HE works best against the skin.

Some sort of shell is often important, in cold, weather, to control evaporative rates and thus provide for some adjustment in heat and cooling.  A big virtue of HE is that it moves moisture so fast that there is a lot of foregiveness in layering.  One can, for instance wear a relatively not-breathable wind layer, to guard against stronger winds and to take advantage of the more limited moisture absorption (relative to soft shell windshirts), and get away with venting via the front zip in warmer and calmer moments.

Something like the Allez Micro also works, decently, as a midlayer over a slower wicking t-shirt, which slows down moisture transport against the skin, but speeds it up through the midlayer.  In this case, there is less wiggle room when it comes to a wind layer, but on something like a spring ski trip where one might have both hot afternoons and very cold mornings (or days), this arrangement might be the best way to cover as many conditions as possible without duplicate layers that can’t all be worn together (for instance, while sleeping).

The Allez Micro is a versatile option, and Montane did well providing the salient details, without anything extra.  Recommended.

The Frank Open 2021

Bonanza to Fenn Ranger Station.  Saturday April 24th, 0600 MDT. (?)

That’s 126 straight line miles.

Here’s what is in my head about this.  First, that is a big route.  Probably close to 200 miles on the ground.  Second, that time frame has the obvious potential to be quite challenging.  Third, and most important, I don’t know much about the area.  I don’t know which trailheads are plowed regularly, which roads get lots of snow machine traffic, how the more open terrain does or does not melt off come early spring.  I have my guesses about all of these things, but a decade of the Bob Open has taught me repeatedly that guesses aren’t ideal for the organizational aspect.  Adding to the complications, the shuttle from one end to the other is massive, and even six months out we’d all be fools to expect anything in particular of the Coronavirus.

For all of these reasons the Frank Open really isn’t going to be an Open in the sense we’ve come to expect.  Even moreso than usual, this is a route I’ve been eyeing for a long time, and if other people want to get in on all or part, that would be neat.  Ideally, and with health concerns permitting, we’d be able to figure out a way to make the driving less irksome.

This is almost a packraft mandatory route.  There are a handful of ways to use bridges, but the rivers (and in late April I assume streams) are several notches bigger than in the Bob.  I chose the start point based on things I want to float, which brings up the second complication, river permits.  Having one for stretches of the Middle Fork will make a lot of sense in many cases.  As of today, there is almost full availability for the relevant week.

This will also be a ski or snowshoe mandatory route, though I am guessing that in a normal year there is a surprising amount of dirt walking to be had.

Evolution of the Tamarisk: Shoulder Straps

First: what the hell is happening with those packs, maan?

A lot.  Unfortunately, almost none of that is helping to get you a pack faster.  While the pandemic hasn’t impacted our family as directly or egregiously as it could, or still might, it has made the world more complicated.  I’ve been and remain on a slightly reduced salary, and our decision in early April for M to go back to work has been wise, in that any financial concerns have been well preempted.  What that has meant day to day is that we juggle our schedules, and that my time has been full enough that choices must be made: kid time, spouse time, meals, work, fun and exercise, yes.  Much else (e.g. cleaning, and sewing), no.

And I am ok with that.

img_9768

Hopefully one of the things we, as a society, get out of the pandemic is an easier time admitting that doing it all, especially as parents, is neither possible nor desirable.

One of the benefits of such mandatory emphatic choices, and of the necessity of managing creeping universal anxiety, has been lots of time in the woods, both on my own and with the little people.  The prototype Tamarisk has been used almost daily, even if that is only to transport rafting gear 200 yards from car to lake, or on a pint sized bikerafting trip (top photo, 5 miles on gravel, 10 miles of twisty and fast class I+).  I am more confident than ever in the design and size, and embracing the extended and indefinite timeline to tweak a few things (the belt could be a bit better, improved attachment points for a PFD).

img_0007

After 6 months of use I remain exceedingly pleased with the shoulder straps, which in packland present a problem whose answer is difficult to properly balance.  Too much padding is certainly a thing, as is too little, too stiff, and too supple.  My old Dana always chafed a little, and never really broke in enough (even after 200+ days) to conform to clavicle and armpit.  The 2012 Gorilla did almost everything right, with the thin foam being a little too stiff, and certainly far too ready to pack out.  The HPG shoulder harness was a study in how far one could get in patterning and conformity, but the Cordura facing against the user chafed and held sweat, and the thin and relatively supple foam let the webbing strap dig in once the load was big enough to stretch the Cordura.

With these three examples as limit posts, I set out a couple years ago to find something well in between them.  Most combinations of foam and materials have worked decently enough, and there is a case to be made for shoulder straps being an ancillary detail to things like the hipbelt and frame, so long as they are good enough.  But the whole point of the Tamarisk is to not just be good enough, and it is easy to recall trips like this one where anything with the least potential for discomfort will sing out to that effect, and loudly.

My current layup for the Tamarisk shoulder straps is a 5mm layer of fairly stiff EVA foam, 5mm 3D mesh turned inside out, and 500D Cordura, with a length of 3/4″ webbing bartacked every 3 inches the whole length.  The result is quite pliable, due to being well under 1/2 an inch thick, yet rigid, due to the EVA.  The thick 3D mesh makes things feel cushy, and wicks sweat (see above), both of which fight chafing during hot 12+ hour days.  Keeping the mesh inside out eliminates the traditional bane of that material, namely the extent to which it traps pine needles and debris, which build up over time no matter the cleaning efforts, eventually becoming abrasive to both clothing and skin.  The greatest cause for celebration is that testing the inverted mesh over the past two years, and this particular foam since January, has revealed no concerns with longevity whatsoever.  img_0010

The packs will come, eventually, but in this age of uncertainty I’m not making any specific promises.

Basal outdoor skills

A few days ago I was exploring some of the exceptional, hidden limestone cliffs we have locally, and following some mountain goat tracks up a scree slope led to option soloing up broken gullies and sticky slabs.  While liebacking off crisp solution pockets and smearing floppy shoes up sharp corrugations my mind went backwards.  To Paul Preuss, Norman Clyde, Herb and Jan Conn.  To ropes that might have broken, slippy ovals without a nose, and pre-War tennis shoes.  To pushing on and up towards that intriguing ridge, guided by experience, an eye for a line, and the necessity of being able to downclimb should those first two come up short.

There is an easy distinction between hard and soft skills in the outdoors.  Hard skills are doing things: tying knots, pitching shelters, taking a bearing.  Soft skills most commonly have to do with group dynamics and communication, but can also pertain to decision making.  Taking a bearing has limited utility if one’s group cannot agree on the best route across a valley, as does a well pitched shelter in a poorly chosen location.  This is all very well, but from an educational perspective I’ve long thought that a third class of skills underpin both the technical and heuristic, giving them both context and coherence.

It turned out that my line did not go.  The progression of ledge and slab ended around the corner in a monolithic line of pockets and implied edges.  I’ll return, some day, with the full sack of modernity, most prominently either a traverse in to a toprope anchor, or bolts.  Or maybe doubles of microcams and pink tricams, triples of small wires, helmet, and healthy fear.  Messner’s murder of the impossible has long since come to pass, with technology and the mindset of 30 years ago requiring a significant leap of imagination to consider the virtues of rock climbing as a pursuit where turnkey safety is not always an option.  The ubiquity and quality of gear has made safety an objective attribute, not entirely on or off, but often quite close to black and white.  As I turned to find a way down it did occur that a rope would have been expedient.  But in the manner of Preuss, for whom even rappelling was cheating, I poked over a series of ledges, downclimbed a tree, scratched across a hanging dirt slope, and jammed down a clean, overhanging corner to the scree slopes, creek bottom, and then the road.  For that hour in the vertical safety was under my feet, and between by eyes and the surface.  Can that smear hold my weight?  Will that flake come loose?  Can I reserve the next 5 moves, if the five after prove too much?

It is easy to view the safety brought on my kinaesthetic awareness, training, and judgment as part of the mechanical skills of climbing, outgrowth of hard skills and sibling to tying a clove hitch or placing a Stopper in an offset crack.  In this account the physical side of not falling is heads to the tails of a sound rope and protection network.  With climbing as the ultimate control sport, an activity in which the brakes are by default stomped to the floor, it is an easy assumption to make.  Whitewater boating is in many ways the opposite of climbing, where flow and the speed and rhythm imposed from without are the default.  Safety in whitewater has to do with instinct and preemption coming together and thus knowing when to stop, and when to let go.  Scouting, setting safety, and portaging can make running a rapid as painstaking and calculated as a 5 hour trad lead, and in either case the structural elements are a best set on a shaky foundation if judgement, self-knowledge, and process, what I think of as the basal outdoor skills, are not solid.

The other week, on Big Creek, we portaged a solid stretch of the crux, a decision which revolved around two burly ledge holes set 20 yards apart.  I had little faith, maybe 10%, in my ability to hit either and not flip.  I had a bit more belief in my ability to hit the precise lines through each feature, and make a big ferry between them.  There were big features both above and below, making the run in complex and the consequences of a swim significant.  I knew my skills, knew I was tired, and knew that I had doubt.  Hard skills were the past decade of paddling, reading water, practicing rescue techniques.  Soft skills were Will and I being honest with each other about our risk assessment.  The basal skills were even more invisible; me calling what part of my fear had to do with performance anxiety, and what part had to do with accumulated fatigue and the doubt over when my clouded mind would enable me to pick good lines in a timely manner.  On my scrambling excursion, hard skills were the past 27 (!) years of off and on rock climbing, especially having previously done moves of a vastly greater physical difficulty.  Soft skills were route finding, looking at the cliff and reading which ledges linked weaknesses, and which ran out in blank slabs.  The basal skills were internal; what percentage of past and current skill was available to me in each moment, how much of my desire to find the ridgetop was tempered by a realistic assessment of reversability?

Writ large, basal outdoor skills have to do with self awareness, and in adjusting goals and decision making day to day and hour to hour to keep them in tune with capacity.  This is how risk is managed on the ground and in the moment, be it the choice to run a rapid, ski a slope, or push forward with an extra 8 miles of postholing at the end of long day.  In a mundane but more pervasive and significant way, basal outdoor skills maintain the integrity of your backcountry functioning by saving mistakes.  Loosing gear, either by letting it fall out of a pocket or by leaving it behind at stops, is shockingly common, and in the case of something like a water bottle, knife, or a good chunk of your remaining food can be significantly debilitating.  Proper nutrition and hydration is both a hard and a soft skill, but the consistent and correct application is just as significant as what you packed, and a basal skill to the core in that constant adjustment to the demands of the moment is success itself.

So too with packing, unpacking, and transitions generally.  Efficiency here can save significant time in the moment, and far more time later in the ripple effect of being able to find gear easily, not forgetting anything, and having the correct items at hand for the tasks of the day.  Each transition during the Salmon River I was somewhere between 30 to 50% faster than Will and Robert.  Part of this was hard skill, experience, having done boat to hike and boat to camp transitions many times more than either of them (Robert, in fairness, was on his first multiday trip out of his kayak).  But I think the majority was basal skill, in that I’ve cultivated and practiced highly purposive transitions for a long time.  It is one thing to quickly and skillfully pack a pack with the same gear you’ve taken on similar trips for years.  It is another to adapt principal to a new range of items and have a coherent enough rig from day one.  In the case of the Salmon trip, I had never put so much inside my packraft on a previous trip, but on the first day I had the right stuff out of the boat for the day of paddling, and had the stuff inside secured and balanced enough that portages and self-rescuing after a swim both went without abnormal difficulty.

I don’t think many adventurers get far into backcountry pursuits without becoming acquainted with the importance of self-management and execution.  I do think many people, even those with considerable experience, consistently mistake both the inherent subjectivity of these skills and more importantly, the exacting moment-to-moment control that dependence on internal processes can provide.  It’s an amorphous thing to grasp, and not something concretely taught, but recognition of basal skills as an independent class which control the application of hard and soft skills will provide more consistent backcountry performance, and thus, safety.

Distance learning

There has been a lot of discussion lately concerning the new, or newly rediscovered, hikers and bikers and outdoorspeople the pandemic has brought out of rooms amongst the trees.  It is logical, and I see it as an extension of the last decades trend of increased outdoor participation in profile, if not as a percentage of the US population in fact.  The OIA 2019 report is padded, as it has been for at least a decade, with activities such as jogging and rv camping which take place outdoors but are not generally associated with the wild.  This last is important because some of the recent discussion concerning outdoor newbies has been about mentoring, and learning.

Part of me wants to welcome them all.  The other part of me wants to scream how members of the tribe can possibly, when we have yet to pass beyond the immediacy of how over-socialized our world is, get things so wrong.  Especially in the age of the internet, when instructions on every mechanics is easy to find.

I spent my whole childhood in southwestern Ohio.  Whenever I’ve returned, especially in the past decade, the logic of the landscape is jarring.  I learned to climb in a gym, learned to hike on vacations and in the strings of woods which clung to creeks around town, and when things got technical I turned to books.  Basic knots from the BSA hankbook, tracks and plants from all of Tom Brown, klemheist and biner block from Freedom of the Hills.  We never got enough snow to self arrest, but by high school had one BD X-15, a drill bit glued to the hole in a claw hammer, and ancient Salewa 12 points in hiking boots and “discovered” the 25 foot vertical ice pillars which formed on the spillway in our local big woods state park.  It was equal parts this DIY period so far from anything and my poorly-acknowledged introverted nature that has kept me on the self-taught path ever since.

Not everyone has this agency growing up, to say nothing of a family system that gives both a safe neighborhood to roam and fancy, fancifully chosen gear for Christmas.  There is a lot to be said, still, for core outdoor adventure being the ultimate encapsulation of first world privilege, in all its expensive and precisely curated discomfort and challenge.  There is a bit less to be said for the high cost of entry to outdoor pursuits.  This doesn’t hold too much water in things like backpacking, where skill and fortitude and thrift stores can provide 9/10s the practicality bought in a $5000 trip to REI.  It does, sadly, in things like boating and cycling, especially the later, which in the past 15 years has seemingly doubled down on eeking more and more profit as the last bastion of unfiltered yuppism.  There is still less to be said for the meritocracy of information, as today the process of learning has never been more accessible.

There is a stupendous amount of crap information, of course, but given that we’re confining the discussion to wilderness pursuits, the judgment learned in discovering bad advice to be what it is is more valuable than the skill of pitching a tent on six feet of snow or climbing a 9 inch offwidth.  My repeated attempts to convey how mindset creates safety are so perseverative precisely because these intangibles are the most valuable and most enduring things I’ve learned from climbing, backpacking, boating, skiing, and everything else.

Picking

In the Bob spring comes first to the junctions, where flat grass melts on the south and ten steps north snow lingers, hollowing into unwalkable with a crust on top nothingness.  Deer and elk pack into the sweet spots, and feed into the 3 percent of that 3 percent of valley, cliffs to cobbles, picking root and bark through the cold.  Walkers, human or hooved, play the angles of warmth as the season beats back the frozen default.

In one such meadow I came across a spread of fur, spangled around a 30 foot circle of mud and wolf tracks.  The rest of the story was a midnight slick faint with blood and hashed clean with grizzly claws, snaking around logs and just over the hump.  Down the hill, the creek.  Under the huge old what used to be ponderosa, a bear on 80% of an elk.  Up the valley as I walked and then skied towards the cornices, visible from 10 miles, the retreating wolves. 

img_9316

Early that evening wind, snow, and my nerves betrayed me.  I made the lake, long in the mind, impatience having turned an early side-hilling error into a skin glopping, out of water battle against inefficiency and haste.  The lake itself was a perfect custard drop, monolithic in the midst of pines and the high ridges, blown craggy.  The lake was, as hoped, chocolate split at the inlet by 3 inches of open water, flowing for 15 feet over dark gravel.  Rehydrated I made the ridge, but the final thrust into the strafed teeth of the alpine was steep and guarded, hollow in the pockets between the rocks.  I probably could have made it up.  I was less sure about making it back down, so I transitioned tentatively next to a ragged tree and hacked back down, fear tinkling away as drove the outside ski hard through each turn, the snow crust shattered and rattled down ahead and along.

I refilled at the magic drip I was sure would freeze into nothing by morning, melted snow to add to my pool of life, and had more minutes as the blue tent faded away to consider beyond the obvious; where my mind had traveled that long day along and apart from my legs and arms and body.

img_9410img_9408

The next day dawned blank, skin and sky only set apart by the opposing line of tree and cliff.  I went down, and like all things in the mountains the matter of factedness held risk.  The trail, which I was determined to hold, moved between aspects, enveloped in old growth fir.  The fear of yesterday passed through, not just turn to turn, but minute to minute.  Skins on, then off.  Boots locked, then open.  Efficiency in complex terrain comes in choices sacrificed to the big picture, in allowing inevitable mistakes to melt in the face of flow and miles.  Confidence, stacked moment to moment. 

And thus, safety.

img_9312

I counted ripstop that night at the lake, and had the weight of the moment and the last decade come together.  Should I be out in the wilderness at all, given the weight of the moment?  More personally, should I be out here, holding on to ambition and learning, when the familiarity upon which that safety is stacked is, increasingly, in the past? 

When I thought back to Isle Royale, mug bogging around the reservoir snow blowing into my face, the answer was easy.  Especially in a world gradually and suddenly shifting forever, the constant process of reminding and refinding me and my place in the world is hard to imagine in any other venue.

Islands of moisture revisited

“…under duress the most important characteristic of your clothing system is not the ability to keep external moisture off you, but the ability to allow internal moisture to escape efficiently without chilling you excessively.”

Me

R0000334

In the ~five years since I wrote the above post, and since Sitka popularized the concept of the rewarming drill.  In that time a number of people have produced trials, and a few significant advances in gear have become widespread.  It is worth taking a look at both.

Rokslide recently published a static rewarming drill trial; jump in a lake, get in a sleeping bag, use hot drinks and hot water bottles to see how your insulation manages moisture.  A useful exercise for the unfortunate but inevitable scenario of having to go to bed damp or wet with no other way to dry out.  This can happen in the alpine, or just because of rainy weather without respite.  The lessons from the Rokslide article are mostly old hat: the lightest possible layers (especially against the skin) with the least possible spandex are best.  Anything beyond mid single digits spandex should be categorically out for backcountry stuff in damp climates, as should merino wool.  Synthetic bags and insulating garments provide a significantly larger margin for error, though in the case of the former weight goes up enough that you can almost buy a bigger margin with a premium down bag.  It’s also worth highlighting that women, especially those who require more support than a basic shelf bra/tank provides wear a significant handicap when it comes to eliminating moisture islands from undergarments.

There are also a few versions of the various rewarming drills, static and active, that might be worth watching if you really care to geek out on specifics.  Subtle but significant lessons here are just how much redundant fabric layers (e.g. pockets) can trap moisture, along with how one poorly conceived layer in the system (most often an inartfully selected mid layer, such as a second heavy baselayer) can slow the whole system down.  This performance during a for-video trial is one thing.  The cost lagging dry time can exact on metabolism and morale on day 3 of 5 or 7 quite another.

The most important development in this area, in the last five years, has been in active insulation (Alpha Direct, left; Full Range, right).  The virtues over fleece are in no small part the much lighter fabric (not necessarily garment) weight relative, which vastly increases dry time when internal heat is driving the process.  The advances in fabrics used for shells here also makes a big difference, as they both preserve internal warmth (and thus, temperature gradient) without too far inhibiting moisture transport.  Being able to get wet, be it by falling in a river or sweating too much on a skin track, throw on an active insulation jacket, and then work yourself dry without too much attention to detail has been a game changer.

Lately I’ve been revisiting classic pieces, like the Rab Windveil and Patagonia Capilene 4, that firmly prioritize not only dry time not very low moisture accumulation even under poor circumstances.  And I’ve been impressed, all over, with how well you can do with a system whose ceiling for error is small.  Heavier baselayers, esepcially wool, can in theory do more and better than Polartec HE, just as a softshell windshirt can breath better than the Windveil and peers.  But it is darn nice to just not have to faff much, to leave the second layer on for that extra 20 minutes up the hill with minimal penalty.  If there is any alteration I’d make to these thoughts, it would be that.

Evolution of the Tamarisk: features

Or; as few things as possible.

Backpack features don’t make up the majority of a packs weight, but they do make up the overwhelming majority of the weight which is easily negotiable.  There is only so much weight to be shed with material (before you sacrifice durability), only so much with suspension or frame elements (before the pack carries poorly), and for a technical backcountry pack good side pockets (and belt pockets) are mandatory.  So the design task left is to make it possible to carry all the technical goods, along with the unexpected and unexpectable, with the least material possible. 

This includes snow gear like skis, crampons and ice axe(s), and a shovel, along with water gear (PFD), and perhaps something odd like firewood or even a bike.

I’ve settled on an extension of the reinforcing layer of bottom fabric, with horizontal daisy chains 15 inches apart.  Each daisy has a second layer of fabric inside.   Not only does each bartack thus have serious resistance to the ends pulling through the fabric, but the load is transferred to the whole fabric panel, and thus 16+ inches of seam.  The sleeve is not primarily intended as a pocket, being non-dimensioned, but is open at the top and thus not a bad place to stash pesky things like paddle blades, but the first intention is to both spread the load and provide abrasion resistance.

Pictured above is the full deal, for a trip which involved a 12 mile hike to even reach the skiing, and ended with steep skiing (on terrible crust) at 8500 feet.  A shorty 45cm ice axe mounted, old school, to a cord loop on the lower daisy.  The shovel shaft went inside the sleeve pocket.  Skis mounted diagonal, with ski straps, and crampons went under the top cinch strap, on top of three days of gear.

The final piece is the top strap, which is bartacked into the middle of the top daisy chain on one end, and with the buckle directly under the upper stay pocket on the other.  When the pack is on the empty side the angle of the strap, combined with the taper of the bag, provides compression.  When the pack is full the strap pulls the load towards the suspension, transferring the load and enhancing stability. 

And that, is it.
