Not all bivies are in the dirt, but when they are, we wouldn't want a better sleeping companion. Wind- and water- (and of course dirt) resistant, it's made of sturdy, pliable nylon canvas (51% recycled) with a DWR (durable water repellent) finish. Insulated with 100% Recycled Down reclaimed from used down products, the vest has wide baffle construction and plush inside trim for extra warmth. An insulated hood adjusts with contrasting cord and the center-front zipper tucks under a wide metal snap placket. Inside print detail on the side-entry handwarmer pockets and secure inner chest pocket. Slight drop-tail hem.
