The men's Smartwool Merino Base Layer Pattern 1/4 Zip gives you the style and versatility you need to take on cold weather.
Smartwool cut this quarter-zip from 100% responsibly sourced merino wool, which helps regulate your body temperature and wick moisture away from your skin. Plus, flatlock seams help banish chafing, especially when you’re shouldering a pack.
One of the heaviest base layers in Smartwool’s lineup, this top delivers peak performance during high-output winter activities.
