The Boreal Forest of Alaska where caribou winter "the long night" is some of the most unforgiving terrain in the world. A place where this vest is right at home. 700-fill-power goose down maximizes warmth without bulk while a durable 1.8-oz. Cordura® shell fabric wears harder than standard taffeta without weighing you down. We’ve even up-armored the shoulders with ripstop reinforcements. Cordlock waist to snug out drafts, stand-up collar, zippered hand-warmer pockets, back locker loop.
