With low-profile seams to minimize bulk and maximize comfort, the slim-fit Women’s Summit Series Pro 120 Crew is an adventure-ready, lightweight base layer made for any type of cold-weather exploration. DOTKNIT fabric helps manage moisture build-up and thumb holes at the cuff prevent the sleeves from riding up when worn with additional layers. This updated version also features 100% recycled fabric and anti-odor technology to keep you feeling fresh.
