Red Rab-off

We outdorks all have our pet gear obsessions. I like to think that mine (packs, shoes, windshirts) are especially practical. Windshirts are important because it’s windy a lot around here, and because I put out a lot of heat and thus try to avoid wearing a waterproof-breathable jacket at almost all costs. Weatherproofing and breathability have an indirect but nonetheless distinctly inverse correlation. Thus the challenge for a windshirt is thus to provide just enough wind and precip resistance, without going overboard.


The Rab Cirrus, pictured above on me at far right, is what I’ve taken to calling a traditional or hardshell windshirt. It’s made of a light, densely woven fabric (Pertex Quantum) and treated with a water repellant from the factory.  Such shells won’t keep you dry in sustained rain, but will shrug off snow and drizzle while venting well enough through the fabric to keep sweat managed.  In warmer conditions (say, above 50F) these windshirts can be not breathable enough.  There are minor variations in fabric durability and DWR longevity (as detailed in my BPL state of the market report), but performance-wise the Cirrus is representative of the majority of windshirts currently available.

What sets the Cirrus apart are the exceptional features and fit.  Rab is currently at the top of the heap of outdoor clothing manufacturers because both their fabrics and designs are tailored to practical outdoor use, as opposed to many of the other A-list names who make many concessions to fashion.  As seen above, the fit is tailored and slim, and arms are long, and the plain hood crafted so that even without cinch cords it sits well and doesn’t interfere with vision provided it is zipped up.  Not seen above, at least no easily, are the twin a-line pockets.  These have easy running zippers, are backed with quality mesh which doesn’t interfere too much with breathability, and are placed such that neither waist belts nor shoulder straps sit over either the openings or the contents.  The Cirrus is simply a pleasure to wear and live in.  In a men’s medium it weighs 4.2 ounces.


The Rab Boreas (above, on orange) is another windshirt of which I’ve been very fond. It’s heavier, at 8.6 ounces in medium, but breaths much better and has proven very durable. The lack of a DWR has not proven enough of a downside to keep it from becoming my most-worn piece of outdoor clothing. The main flaw is that the high spandex content in the fabric has the Boreas drying rather slowly.


Because I can never leave well enough alone in this area, I recently purchased a Rab Alpine jacket (pictured above) to continue my search for the most versatile windshirt.  I may have found it.

The Alpine has all the features I would want in any serious-weather shell, and executes them perfectly.  The pockets are identical to those on the Cirrus.  The hood is big and adjusts around the face and across the back of the head; it is functional with a helmet and a bare head.  The arms and torso are long, even moreso than the Cirrus.  The hem has a full cinch cord, and the cuffs are simple elastic which is snug enough for bad weather but flexible enough to pull up over your elbows for venting.   The main zip is a #5, which I’ve found to be much more durable than the increasingly common #3s (like that on the Cirrus).  The real guts of the Alpine is the fabric, Pertex Equilibrium.  Equilibrium is a denier-gradient nylon, meaning that the outer face of the fabric is tight and DWR treated, while the inner is gently textured, which increases moisture uptake.  This means that the Alpine wicks and dries very fast.  I’ve yet to quantify it, but I think the Alpine wicks faster than the Boreas, and dries faster when soaked than the Cirrus.  Equilibrium is a bit lighter than the Boreas fabric (115 grams per meter compared to 131), and even with all the features the Alpine weighs 7 ounces in men’s medium.

If, as I suspect it will, the Alpine equals the Boreas in warmer-weather breathability the things holding it back from replacing both will be few.  Durability will be one, with the Boreas having proven surprisingly abrasion resistant.  Equilibriums greater air permeability, when compared to something like the Cirrus, would seem to be a potential disadvantage under nasty conditions, but I don’t think that will prove to be the case.  The shortcomings of light windshirts in serious wind has a much to do with the pumping effect promoted by light fabrics than air permeability of the fabrics themselves, and thus there will likely always be a place for stiff Goretex and the like.

Rab Alpine jacket; get one. Red isn’t a bad color, either. Not stealth, but it will make is easier for your ski partners to see you through the trees and fog, and keep you from getting shot off your bike during hunting season.

  1. “Get one” +1

    I have a Cirrus, Boreas and Alpine and love them all but the Alpine is the daddy. I wear it more than any other coat I own including every commute when it isn’t raining. Fit, fabric, construction and features all A++. Excellent hood, long arms, right length, perfect collar, fantastic compromise/balance fabric, nailed-on pocket layout. I’ll be buying another for sure, and in a brighter colour. My current ‘Beluga’ grey/blue version is great for feeling incognito around town but it lacks punch in the outdoors.

  2. I’ve been trying to find one of these in a small for over a year. No luck. It doesn’t help that it’s named so poorly in terms of search. ‘Rab Alpine Jacket’ matches almost every jacket they make. My vapour-rise lite has become my most worn layer this winter.

  3. Endurance is a nice fabric, I have a made a baseball cap from it. However, when I used it a couple of years ago (things might have changed) it was less wind-proof than Quantum and had pretty poor resistance to abrasion. All qualities that might be an advantage on some occassions and a disadvantage on other.

  4. I also have those 3 rab wind shells. All bought on sale. I’ve teared part of the sleeve of the cirrus when I took a fall slide climbing in the ADKs . Pinholes appeared pretty fast after a couple days of use. The alpine, exept from a lot of piling on theback (inside the jacket) has been proven durable to off-trail hiking. For exempla, last week, my friend’s atom lt (don’t ask me why he was using it…) was destroyed while snowshoeing offtrail in the dak’s (lots of spruce) while my rab alpine held up perfectly fine.
    As noted by everyone, fit is super, esp. compared to patagonia for me.

    1. woah, sorry for all those typos, wish I could edit that!

    2. No worries with typos, I embrace them out of necessity.

      The shell fabric on the Atom is one of the things I meant when I wrote about concessions to fashion. Patagonias stochastic approach to sizing is another.

  5. I’ve had my eye on the Alpine for a couple years. I’ve been considering it or the Arcteryx Squamish for a more breathable replacement for my Houdini. Gabe, you might check with Second Ascent in Seattle. I was up there over Christmas and they had a bunch of them. I think they were an older version (might have even been the pullover, can’t remember) but they had several smalls. Might be worth giving them a call.

  6. I have made a couple posts on BPL over the last 18 months about this hoody. It’s really amazing. The fabric is pure voodoo. I wore it a few months ago in heavy sustained rain for about 3 hours before it catastrophically wet out. Threw a Rab Kinetic on over the top and was good to go. Despite being wet the Alpine acted as a decent midlayer 40 and raining. I was wet but warm. Breathes great, perfect hood and sleeves and wicks like crazy. Got it caught on some thorny business in Joshua Tree but the Alpine had no damage. I overlooked the weight because of the wicking function. Best, most used coat I own.

  7. […] they’re tougher than most think). An example would be the Rab Cirrus, which I discussed here. The recent trend of light softshells, like the Rab Zephyr, typically use a poly/spandex blend. […]

  8. […] Windveil is cut from the same pattern (literally, I would guess) as the Rab Cirrus.  Same skinny torso, same long sleeves, same drop tail, same great hood, same nice chest […]
