Smartwool Merino 250

With the Merino 250 Base Layer Bottom for men, your ski, hiking, and running shoes stay free from friction and bulk. Made from 100% responsibly sourced merino wool, it offers ultimate breathability and comfort, while the newly designed fit of the base layer pants reduces sagging and excess fabric—perfect for your layering needs. Merino wool with interlock knit enhances comfort, breathability, temperature regulation, and odor resistance. The updated fit improves functionality while enhancing aesthetics. It features an elastic waistband with a merino coating and traditional slit design. The flatlock seam construction minimizes friction. This heavier, soft merino wool fabric provides breathable warmth, wicks moisture away from the body, and ensures a pleasant feel against the skin in colder temperatures. Knitted in Vietnam.
