We didn’t overhaul the Snowpack Stretch Down Jacket – we just taught it a few new moves. Specifically, your moves. One of the main things anyone needs when they’re cross-country skiing or snowboarding is unimpeded movement. So, we dialed that up in the Snowpack. The nylon/spandex fabric offers all new levels of contortion and comfort so you can shred powder, not seams. Inside you’ll find the same 650-fill goose down, nature’s greatest insulator, with some added reinforcement. The Snowpack has been mapped with zoned insulation – synthetic in place of down in high-sweat areas. Since goose down doesn’t do well wet, using synthetic insulation in places like the pits, sleeves and collar sidesteps the dreaded sweat-then-freeze experience. Without sacrificing an ounce of packability or the Waterflect® DWR finish. Step in and zip up.
