Smartwool's Merino 150 Base Layer Bottoms work hard year-round to keep you comfortable everywhere from the slopes to your campsite. The ultra-smooth Merino helps regulate body temperature, breathes well, and naturally resists odors when you're wearing these base layer pants. They've 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.

Merino 150 - This breathable, soft, lightweight fabric offers next-to-skin comfort, moves sweat away from the body, and acts as a versatile performance layer for warmer conditions.
