Made from an innovative blend of wool and nylon, the Backcountry Matilda Baselayer Bottom is an ideal base for active pursuits on snowy winter days. Nuyarn wraps merino wool around a nylon core, giving you soft next-to-skin comfort that's warm, durable, and layers easily beneath your ski pants. And while thermal comfort might be the name of the game, the fabric is also moisture-wicking and odor-resistant, so you can play harder and stay out longer.
