Adventure awaits. A snug-fitting midlayer made for backcountry missions and all-mountain warmth, our women's Drift Tech Fleece features lightweight polyester with a touch of spandex for snug-fitting warmth. Zip-up side pockets let you stash stuff securely, while thumbholes keep your hand toasty while adjusting boots and more on the trail. Wear solo on the way up, add a shell on the long, whooshing way down.
