Smartwool Classic All-Season Merino Base Layer 1/4 Zip Men's

Whether you're breaking trail on a frosty morning or paddling into a cool headwind, the Smartwool Classic All-Season Merino Base Layer 1/4 Zip earns its spot as your go-to layer. The All-Season-weight Merino fabric wraps around a nylon core, so you get the natural temperature regulation and softness of 100% Merino wool next to your skin, plus the added durability to handle repeated wear under a pack or drysuit. Flatlock seams and an offset shoulder and side seam construction keep chafing to a minimum, even on long days on the water or the trail, while the wrap-front side seams and slim, body-following fit let you move freely without bunching fabric. Pull the 20 cm center-front zipper down when you heat up on the climb, then zip it back up when the wind picks up on the summit or the takeout. It is comfortable, hardworking, and genuinely built to do it all, season after season.
