DESCRIPTION
KNOWLEDGE GAINED
Serious mountain travel requires an insulated piece with exceptional warmth-to-weight value. The Fission SL is our lightest, fully waterproof, insulated jacket that is outstanding in cold wet weather.
THE SKIN YOU'RE IN
GORE-TEX® 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.
NEVER TOO WARM
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.
FINISHING TOUCHES
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.
