Smartwool Classic Thermal Merino Base Layer Bottom Men's

When the mercury drops and the trail, slope, or road turns cold, this is the layer that keeps your legs in the game. Smartwool built the Classic Thermal Bottom from its heaviest weight 100% Merino wool fabric, so you get serious warmth without feeling weighed down. The interlock knit construction breathes well and moves sweat away from your skin, so you stay warm and dry whether you're climbing a skin track, chasing a winter PR, or hiking through fresh snow. A slim fit updated for better function and a cleaner look layers easily under shells and softshells, while the Merino-covered elastic waistband and traditional fly design add everyday comfort and convenience. Flatlock seams lie flat against your skin to cut down on chafing over long days out, and Merino's natural odor resistance means you can wear this layer hard without worrying about it wearing on everyone around you.
