Classic Thermal Merino Bottom delivers breathable warmth for winter adventures

What Our Gearhead® Experts Are Saying:


“These baselayers are my go-to when the temps drop below freezing. They’re soft, warm, and never itchy. Even after a full day of touring, they wick sweat like a champ and still smell fresh enough for the après.”


When the air turns crisp and the trail dusts over with frost, we rely on the Smartwool Classic Thermal Merino Baselayer Bottom for unmatched warmth and comfort. Crafted from 100% merino wool, this heavyweight knit regulates temperature naturally—keeping us warm during dawn starts yet breathable when the day heats up.


Merino’s soft, itch-free fibers wick moisture away and resist odors, making these bottoms perfect for back-to-back ski days or multi-day winter treks. The interlock knit enhances stretch and durability, while flat merrow seams and a merino-lined waistband prevent chafing for all-day ease. Whether layering under ski pants or wearing solo at camp, this baselayer keeps us cozy, dry, and ready for anything the cold brings.
