All the warmth without the bulk. Inspired by a vintage oakley piece, the men’s hyland o-puff vest is a high-collar, quilted piece filled with 3m ™thinsulate ™insulation for thin, lightweight warmth. We treated the vest with hydrofree dwr to shed fabric moisture and prevent cold, clammy skin, and waterproofed the material for the ultimate winter-ready layer. Zippable hand pockets let you stash mitts and more, an adjustable drawcord hem helps retain heat.
