When plummeting temperatures chase the crowds indoors, pull on the Norrona Men's Wool One-Piece Long Underwear and take advantage of having the mountain all to yourself. Made from merino wool and a touch of nylon, this baselayer offers the perfect combination of comfort, durability, and moisture-wicking power. Made for a variety of alpine activities, this one-piece suit will keep you warm at different activity levels. Zippers on the outer thigh let you dump heat fast when things start to heat up. A fitted hood provides extra protection from clawing cold. Wool's natural resistance to microbial growth reduces smell, so you'll be able to take it on your 3-day hut trip and not hate yourself by the end.
