Blue skies, sparkling snow-capped evergreens, fresh tracks--we're excited to get back out there this winter. As a first step we'll be pulling on our Backcountry Spruces Merino Long Underwear. A unique blend of wool and nylon make these performance tights both durable and soft. Merino wool is an over-achiever, actively regulating body temperature, wicking moisture, and fighting odors, so we can work hard and play harder.
