Terramar Merino Mens Wool Pant

"Two-layer pants trap heat generated by your body yet still allows moisture to move freely away from your skin. This is accomplished with two distinctly different fabrics. The Soft Spun EC2 polyester draws the moisture and warm air to the next layer where the Merino wool holds the warm air back and lets the moisture move to the outer layer where it can evaporate. Black (BLK). S(28-30), M(32-34), L(36-38), XL(40-42)."
