Smartwool’s best-selling and warmest base layer has been refined for an even better fit. The Merino 250 Base Layer Crew now features chafe-free flatlock seams and shoulder panels designed for extra comfort under a pack. Made from 100% Merino wool, it naturally regulates temperature, wicks moisture, and feels luxuriously soft against the skin. Wear it on its own in cool weather or layer it in colder conditions for reliable warmth and comfort.
