What Our Gearhead(R) Experts Are Saying:"I wore this on a ski tour with a lot of elevation change, and it handled the transition from sweaty skin track to cold ridge line better than any fleece I've used. The thumb loops kept my sleeves in place under gloves the whole day."Rapid elevation changes ask a layer to work both ways, and the HIMALI Endeavor Fleece Jacket handles that shift without missing a beat. Climb a skin track at a steady clip, and the 157 gsm fleece wicks sweat fast enough to keep you from overheating, then holds onto warmth the moment you stop moving at the top for the transition down. A helmet compatible hood moves with your head instead of fighting it, keeping your field of vision clear on technical terrain, while integrated thumb loops anchor the sleeves in place under gloves. Large zippered hand and chest pockets keep essentials secure through every kick turn and traverse, rounding out a fleece built by someone who's tested layering systems on all fourteen of the world's 8,000 meter peaks.
