When we venture into the backcountry, we rely on the Marmot Solitude UL Bio Jacket to keep us dry and comfortable as we ride through deep troughs of powder. The bio-based PU membrane protects us from wet, heavy snow and winter storms, and the breathable, lightweight nylon stands up to snags and hard spills. The jacket is built specifically for the backcountry, with RECCO reflectors helping to improve our safety in variable conditions, and large underarm zippers regulating our temperature during long, grueling climbs.
