SmartWool Midweight Pattern Crew Men's

When you're post holing up the side of a mountain on your way to an alpine yurt, you need a quality technical baselayer like the SmartWool Midweight Pattern Crew between your skin and everything else. This merino long underwear top helps your body stay cool when you're working up a sweat, and it keeps out the cold when you're flying down the mountain. Flatlock seams prevent irritation, shoulder panels let you move freely, and UPF 50 sun protection keeps your skin safe if you're not wearing a shell.
