The Flylow Vector GORE-TEX 2L Jacket is built for skiers who've written off insulated coats as too warm to move in. GORE-TEX two-layer fabric blocks wind and water through a storm day, and 60 grams of Primaloft Black Eco insulation adds real warmth for standing around at the top of the lift without the bulk of a heavier midlayer. Underarm zips open up when the pace picks up, venting heat before the jacket turns into a sauna on the climb. A 3-way adjustable, helmet-compatible hood and a removable powder skirt round out a coat built to work both at the resort and past the ropes. What Our Gearhead(R) Experts Are Saying:"I unzip the underarm vents the second I start climbing, and they dump enough heat that I'm not stripping layers halfway up. Standing at the ridge afterward, the insulation kicks back in and I'm not shivering waiting for my partner."
