Warm, durable, and ready for action on the slopes.

You never miss a ski day regardless of the conditions, and the Arc'teryx Men's Fission SV Insulated Jacket is the reason why. A Gore-Tex membrane, fully taped seams, and WaterTight external zippers keep you dry in the wettest weather, and Arc'teryx added Gore-Tex Pro reinforcements in high wear areas for long-lasting durability. Coreloft insulation brings the warmth without the weight, and it leaves the jacket with exceptional breathability so you stay comfortable during intense ski sessions.

An expedition fit with e3D patterning leaves plenty of room for layering without restricting your movement, and a longer length covers your butt even when you bend over. Articulated elbows give the freedom of movement you need when you ski through trees. The insulated DropHood rotates with your head for total visibility, and adjustable cuffs and hem seal out the cold and retain all that wonderful warmth.

  • 2-layer Gore-Tex, fully taped seams
  • 40D Nylon ripstop shell
  • 140g Coreloft insulation in body, 100g underarm
  • Expedition with e3D fit, thigh length
  • Articulated elbows
  • Insulated DropHood

  • Gender: Male
  • Familiarity: I've put it through the wringer

QUALITY: 10/10
FEATURES: 9.5/10
STYLE: 10/10
WARMTH: 8/10

I'll be honest. I'm more of a city guy than a backcountry guy. I like the look, design, and feature set of "official" adventure clothing, though I rarely use such clothing for its intended purpose. When I indicate that I have put the Fission SV "through the wringer," I mean only that I have used it as my primary winter jacket in Kansas City for the last 3 years (and recently bought a new 2013/2014 model). That said, it has exceeded all of my expectations. The warmth-to-weight ratio is perhaps its best asset, as I hate heavy jackets but run cold, and this jacket keeps me very comfortable down to approximately 10 degrees F with only a sweatshirt. (An older model that used 200g/m2 of Primaloft Sport (clo = .79) was even warmer, but the 140g/m2 of Coreloft (clo = approximately .92) used in the current model is still excellent and, I estimate, about 80% as warm.) Intelligently oriented cinch cords permit the hood to be dialed in perfectly to my helmet-less head. The extra-long length in back keeps my seat perfectly covered, while a newly-added, hem-level skirt perfectly seals out cold air. A total of 4 external pockets (2 chest, 2 handwarmer) keep everything handy without the need to unzip my jacket to access either of the 2 cavernous interior mesh pockets. And, of course, Gore-tex lends waterproofness and windproofness, which provide incalculable, self-evident value. While I believe the Fission SV is worth every penny of its asking price, it is still not perfect. I believe future design tweaks should include a neck cinch around the insulated collar, softer/less-stiff microfleece chin/beard guard, microfleece lining around entire interior collar, complete microfleece lining of hand warmer pockets instead of half-lining and, finally, use of more Coreloft insulation so the jacket is as warm as earlier models (through 2011) used to be.

Warmth with a bit of style!

  • Gender: Male
  • Familiarity: I've used it several times
  • Fit: True to size

Needed a new winter coat for the Boston winters and am so far thrilled with the Fission SV. The jacket is warm and is easy to layer under without creating to much added bulk or limiting motion. I am 5'10", 179lbs, athletic build and ended up with the Large after trying both the L and the M. This is the one part of the jacket I think they may need to consider redesigning...the M fit well in shoulders and sleeves but was noticeably "snug" around my hips and thighs. I am a 34 inch waist so this seemed a bit odd. The Large, while being a bit long in sleeves and roomier in the shoulder, fit much better overall AND allows for greater layering capabilities. I have already been out in 20F weather with a t-shirt and mid-weight fleece on under the jacket and could not feel any of the cold. Love this jacket!

Good jacket

  • Gender: Male
  • Familiarity: I've put it through the wringer
  • Fit: True to size

Been looking around at a tons of jacket companies (eg spyder, outdoor research, mountain hardware, black diamond, mountain equipment) and settled with this one because it was light, somewhat insulated, and goretex pro. This was probably the best multipurpose jacket for me. I do a lot of hiking during the winter times and living in NYC, I wanted something warmer and water resistant instead of my Uniqlo Ultra Light Down jacket. Some issues with the jacket, the handles for the zippers, they do need to be thicker/bigger. I don't mind it as much because I use glomitts, but for people just wearing gloves, this can be an issue. Another issue is the front edge of the hood, the string to tighten it bends the edge of the hood and could permanently have a crease in it. It should be made with thicker material so it doesn't warp/bend so easily. Snowskirt is another issue, not a deal breaker for me but I understand why it wasn't included, has to be marketing. If the next version of this jacket includes a snowskirt, I will be pissed =P Size is true to sizing chart. Standing around in 25F with 10 mph winds, feels like 10F, keeps you okay, need to layer inside though (i usually wear a undershirt, a uniqlo long sleeve heattech shirt and a thin sweater from BR), t-shirt alone is not enough. At the dog parks, when standing around, I sometimes wear the Uniqlo jacket on the inside and the fission jacket on the outside, and for me, that's enough and still very light. This jacket along will not be good enough for Iceland or Churchill Canada, you must layer.
