Marmot Haven (2p) by the numbers

I’ve been using trekking poles less and less in the last year, which creates something of an issue as they’ve become the cornerstone of most UL shelters, including the Shangri La 2 we often use.  A paddle works for larger mids, but having it in the middle can be a bit of bummer for couples camping insofar as it makes cuddling rather peculiar.  M also requested more useable headroom than the narrow SL2.  I’ve become a big fan of the flexibility of floorless shelters, so when the Marmot Haven started coming up on sale we thought about it for a while, then snagged one.

It’s a strange critter: an elongated octagon supported by at least six stakes and one long arching center pole.  There’s a single zip door along the pole at one end, two big zippered vents in the ceiling, and a clip-in full sized floor.  The Haven is really big, 3 meters long and 260 cm wide.  Though marketed as a two person shelter, it would sleep three with no problem.  For two the space is excellent, with the sloping walls making the sides not good for humans but excellent for stowing lots of gear.

The canopy and floor are made of 30D ripstop, with a heavy PU coating on the inside and silicone coating on the outside.  The burly coatings make the fabric seem heavier than standard 30D, a fact reflected in the weight.  Stock the canopy was 37 oz.  I cut off the excessive adjusters on each corner (compare below to above), leaving a mere webbing loop and length of dyneema cord for staking.  Given how awkward the sloping sides would have made adjustment from inside, this really isn’t a functional impairment.  All the seams are factory taped save the ones right above the door and vents (too tight for the machine I guess) so I sealed those, as well as adding dabs for reinforcement to all the tieouts, guy points, and pole clips.  Most significantly, I added two guy points along the center side seam (visible above).  This isn’t meant to be a serious storm shelter, and around here I worry more about wind than snow loading.  With the pole parallel to the wind I think it will remain quite slippery, but wanted to guard against shifting winds and side panel deflection.  All these mods knocked off a bunch of weight and added a fair bit back on, with the final product at 33 oz exactly.

The long pole itself is 8.2 oz.  The stock floor is 18.6.  Stock it comes with various stuff sacks, a pole split, and 10 generic aluminum needle stakes.  Functional in hard soils, but I prefer MSR groundhogs most of the time.  After last weekends slug attack and the promise of a bad mosquito season, building an inner tent with full mesh and a bathtub floor is next on the project cue.  The final product, with pole fly and inner, will be over four pounds.  Hefty by recent standards, but modular, spacious, and very easy to set up.

This isn’t any sort of final answer to making a ‘mid without the mid, of having a floorless and modular light shelter with good storm resistance and no center pole, but might be a good step in that development.  Ongoing reports once we get this in more serious weather will be linked back here.

  1. Although seemingly a minor issue in the store and easily overlooked, we quickly found out that a center pole might as well be the Wall of China for couples. We love the new BD shelter for a lot of reasons but that center pole is couples-annoying.


  2. I picked up an SL2 (with the bug part) on sale at Golite. I love that shelter/tent muchly.

  3. This looks like a nice sheltor, but in my experience women prefer a double walled tent with a floor, at least that is the concensous amongst the many women I have taken into the backcountry. So for me that means I take a Big Agnes Flycreek SL3 when the ladies are with and any of my other shelters when I am solo. Good luck with the inner tent build… I am itching to start a project as well.

    1. While I might *prefer* two walls and a floor, I’ve come to understand some slightly more complicated math, it goes like this – if the tent is lighter and/or smaller, there is more room in D’s pack for him to carry more of the food, cooking stuff, sleeping bags, my personal effects, etc. This is good for two reasons, a) it makes him a little slower and a little less infuriating to hike behind, b) it makes me a little faster and a little less infuriating to hike in front of! Only so much fits in D’s pack, so the less tent, the less I have to carry :)

      Also – previous to this past weekend I had never experienced a slug attack… this will change things!!!

      1. I can’t stop laughing… the image I have of the slug attack is very entertaining :) Good luck avoiding those in the future.

  5. Peggy and I spent several months in a center pole Go Lite Hex while packrafting in various corners of the world a few years ago.
    We found that the adjustable Sawyer paddle placed offcenter to the side to free up space worked fine unless it was a heavy wind. Off to the side meant we had room to pair bond and cuddle and generally stay warm. yea it is a tiny asymmetric but it worked great.
