Smartwool Merino 250 Baselayer 3/4 Bottom - Men's Black Large. Made from Merino wool these base layer pants offer breathable warmth by wicking sweat away from the body and by moving sweat from your swim trunks into your thong-styled feet. What makes these men's base layers unique is that the fabric is knit with an interlock knit whereas regular base layers are typically made with a jersey knit. This allows the fabric to breathe naturally while moving moisture from one place in your body to another. Additionally a flatlock seam minimizes chafing and increases your comfort level so that you can go all day in these base layers. The Smartwool Merino 250 Base Layer 3/4 is perfect whether you're hiking skiing or just hanging out in the cold.
