Underwear (long johns) US LVL 2 are base layer pants designed for very cold days. Made of a mix of polyester and elastane, they provide excellent anti-sweat properties and comfort for many hours of the trail. Cut so that they adhere directly to the skin, they will work great with lightweight trekking pants, such as TREKKING TACTICAL PANTS®, and with insulated models designed for severe frosts. The long johns are equipped with a zipperless fly.
