Smartwool Men's Classic All Season Merino Base layer Long Sleeve

Our most versatile year-round fabric features a nylon core for durability, while keeping soft 100% Merino wool next to skin.

Spring skiing or summer camping? The year-round Men's Classic All-Season Merino Base Layer Long Sleeve is game for either. With our Core Spun technology, we've wrapped lightweight Merino around a nylon core for added durability, while still keeping the comfort of ultra-soft, responsibly-sourced Merino next to skin. We added smooth flatlock seams to help minimize chafing and offset shoulder and side seams to lie smoothly beneath pack straps. No matter the season or the activity, this base layer is made for it.
