Muscular Guys beware!

  • Familiarity:I returned this product before using it
  • Fit:Runs small

All, the sizing on this jacket is about what you'd expect in the arms and body length. The waist drawcord makes the length quite manageable, and the two-way central zipper is on the European side. I thought the fit and finish on this jacket was every bit the equal of Arcteryx, and the eVent breathes a ton better.

If, on the other hand, you are relatively muscular in the shoulders and have a long (side-to-side) back, you'll be disappointed by the amount of room in the arm pits. The back and chest fit well, the sleeves were true to length so far as i can tell, but the "arms up" cut of the arm pits leaves a lot of fabric remaining to bunch up and chafe with just a t-shirt on. I will size up to XXL despite being 5'8 and 195 with chest dimensions slightly under the recommendations (45" vs. 46"). Based upon how difficult I am to fit, i don't hold it against the manufacturer.

If this doesnt work for you, I'd recommend a serious look at Montane- another english company that fits broader-shouldered men better. Hopefully more of you will try Montane and encourage Backcountry to order more of their shells- if for no other reason than for comparison.

I found the hood on my Montane Superfly XT to be better than this one, but the wire peaks in both were excellent- just be advised that the adjuster cords for the hoods will dangle over your collarbones and the drawcords for the waist zip are inside the handwarmer pockets. The central storm flap was awesome in this jacket, as were the interior pocket details.

If you are a tall, thin, or have the typical wiry build of mountain climbers and endurance athletes, you may have found a winner.


  • Familiarity:I've put it through the wringer

I've used this jacket for the past two years after a slew of gore-tex jackets which all seemed to wear out prematurely- losing their water proofness and tearing.

Primarily I use it for ski mountaineering and also easier alpine climbing. The jacket is cut in such a way that the sleeves are plenty long enough when reaching above your head and the tail doesn't ride up either. The pit-zips are large and offer really decent ventilation on the skin track.

One major con, and the reason why I only gave it 4/5 stars is that the hood doesn't fit either of my helmets (Sweet's Rooster and Grivel air-tech)


    Bought this jacket last winter and have now had a chance to test it in the snow and in the mountains. I love the hood, it has great visibility, the wire brim is nice to have to adjust the arc of the hood. It will get warped when you pack it but you can simply reshape it, i don't know how this will hold up over time. The material is very tough, and the quality is fantastic. This is my first eVent shell and so far i have no cons to list and DWR finish seems to be holding up. The fit is good and i seem to have good range of motion when skiing and mountaineering. It may weigh a bit more than some comparable Arc. shells but the jacket is built for harsh rough conditions. A point to note, i'm 5'10" 165, athletic build with broad-ish shoulders. I ordered a medium. The overall fit is good and not to baggy, but I sense the shoulders can be a tad tight if I layer a lot underneath it.

    sizing and features

      caveat, this is a new purchase from Backcountry and has only, so far, been worn on a few windy afternoons. A word on sizing - this jacket runs true to size if you like a relatively narrow fit. if you plan to do any significant layering underneath, you might consider buying a size larger than you ordinarily would. i sized up and was pleased with the fit.

      top to bottom, a great jacket. it's a full-featured heavyweight that might not appeal to the minimalist - i'm guessing it weighs about 24 ounces, where a minimalist hard shell might be 13-15 ounces. it's easy to adjust the hood, and i like having a wire in the brim. if you want to roll up the hood and keep it out of the way, it has one of the best hood-roll flaps i have seen. with the extra weight come more details. four very usable outer pockets, two inside mesh pockets, one zippered, the other for a water bottle. It also has zippered armpit vents, which i like, but my experience with eVent is that one need not vent as much. the front zipper is backed by a flap, and all the zippers are water resistant. tightening the waist-level elastic cord was initially confusing, the pull tab and cordlock is inside and at the back of the larger outer pockets.

      this jacket makes me look forward to bad weather.
