Year-round, ultralight versatility
Spring skiing or summer camping? The Classic All-Season Merino Base Layer Long Sleeve is game for either thanks to the body temp regulating and no-stink properties of Merino. Featuring Core Spun technology, Smartwool has wrapped Merino around a nylon core for added durability while still keeping the comfort of ultra-soft Merino next to skin. Smooth flatlock seams help minimize chafing and offset shoulder and side seams lie smoothly beneath pack straps. Performs well on its own in warmer temps or layers up easily when cooler weather rolls in.
Formerly known as the Merino 150 Base Layer Long Sleeve. Packaging may have either name but the product is identical.
