The Flylow Avery Jacket pairs a Lux two-layer hardshell with mapped Greenloft recycled insulation, running heavier through the body and lighter through the sleeves and hood to keep the torso warm without weighing down the arms. A 20k waterproof and 20k breathable rating holds up through sustained storms, while a PFAS-free DWR finish keeps the face fabric shedding snow all day. Underarm vents, a helmet-compatible hood, and a removable powder skirt round out a jacket built for full days at the resort. What Our Gearhead(R) Experts Are Saying:"I forget I'm wearing insulation until I check the vents on a bluebird lap, because my arms move like they're in a shell, not a puffy. That balance is what keeps me reaching for this jacket on cold, active days at the resort."
