The Flylow Albert Jacket solves a problem familiar to anyone who's sweated through a climb only to go cold the second they stop moving. A 60-gram Primaloft Black Eco insulation, made from post-consumer recycled plastics, adds warmth without the bulk of a heavier midlayer, while a 20k/20k waterproof breathable membrane vents heat and moisture on the way up so the jacket doesn't turn into a sauna. Wrist gaskets and a quilted interior seal out snow and cold air at rest, and a removable powder skirt adapts the jacket from a storm day at the resort to a warm-weather tour. What Our Gearhead(R) Experts Are Saying:"I've climbed in this without unzipping once, then stood around at the top in the same jacket without reaching for a puffy. The insulation holds heat right at the point where I'd normally start shivering, not a minute before."
