The Waas LT ALLIED Down Vest combines a recycled ripstop shell with 600-fill ALLIED goose down for a day that moves from the chairlift to the sidewalk without a wardrobe change. LT means a deliberately lighter build inside, with less down volume and smaller baffles than a standard piece, so the vest folds down small instead of eating up the whole bottom of a bag. What Our Gearhead(R) Experts Are Saying:"I stuff this into the side pocket of my ski pants on the way up and never notice it's there until I need it. Ten seconds after the lift stops running, I've got it zipped and I'm not cold."
