Smartwool's Classic All-Season Merino Base Layer Bottom works hard year-round to keep you comfortable everywhere from the slopes to your campsite. Their ultra-smooth Merino helps regulate body temperature, breathes well, and naturally resists odors when you're wearing these base layer pants. Smartwool has added smooth flatlock seams to help minimize chafing, a wide fabric-covered waistband to fit you just right, and a nylon thread core for added strength—giving you the right tights to go farther than ever before.
Formerly known as the Merino 150 Base Layer Bottom. Packaging may have either name but the product is identical.
