Here's what other sites are saying:

The Women's Fission SL Jacket is Arc'teryx's lightest, fully waterproof, insulated piece for skiers, alpinists, and climbers. Its Gore-Tex shell provides guaranteed waterproof protection that's still breathable for your comfort, and Thermatek insulation is a continuous, hydrophobic filament that ensures even distribution and water-resistant warmth. The Fission's athletic fit includes articulated elbows and gusseted underarms for a full range of motion. This jacket also features zippered underarms for ventilation, and the StormHood is insulated and adjustable as well as helmet-compatible. Arc'teryx also equipped the Fission with WaterTight external zippers for additional weather protection that most jackets don't have.


The Arc'teryx Fission SL Jacket is for serious mountain travel which requires an insulated piece with exceptional warmth-to-weight value. The Fission SL is the lightest, fully waterproof, insulated jacket that is outstanding in cold wet weather. GORE-TEX Pro Shell full storm weather protection is teamed up with our exclusive laminated ThermaTek non-quilted insulation. The result is evenly distributed warmth that can stand up to anything. No cold spots. There are times when you're working hard but you can't or don't want to remove your insulation. Pit zips let you vent heat rapidly, extending usability on cold days. The insulated StormHood takes care of wind and storms with a fully secure, helmet compatible shelter. Often this is the at base camp or sitting out a storm piece, so we've included two zippered hand pockets, two internal mesh dump pockets, WaterTight Vislon centre front zipper, and an invaluable hem drawcord that allows you to really bunker down and have what you need at the ready.
