Built from an innovative blend of wool and nylon, the Backcountry Spruces Merino Long Underwear brings thermal performance to all your snow-covered adventures. Nuyarn takes merino wool and wraps it around a nylon core, giving you a durable fabric with soft next-to-skin comfort--one that layers easily beneath your hardshell pants. In addition to its temperature regulating benefits, wool is also moisture-wicking and odor-eating, so you can work hard and play harder.
