Layered under a hardshell on bone-chilling ski lift rides or as an outer layer for cool fall nights in camp, the Helix Long Sleeve Zip Hood provides technical, sustainable warmth when you need it most. The Helix features a 100% recycled polyester shell as well as stretch side panels to improve mobility and regulate body temperature. Inside the Helix, we used our innovative 70gm MerinoLOFT™ insulation, a sustainable and high-lofting alternative to synthetic fills made from all-natural merino wool (up to 10% of which is recycled). MerinoLOFT™ retains warmth when wet and naturally helps regulate body temperature to keep you comfortable. Zippered hand pocket store cold hands and small essentials.
