The Smartwool Merino 150 Base Layer Long Sleeve is built for year round adventures. Featuring Smartwool's Core Spun technology, lightweight Merino is spun around a nylon core to increase durability while still retaining ultra-soft, next to skin feel. The 150 weight merino is highly breathable, odor resistant, and incredibly comfortable next to skin, making it ideal for warmer conditions or high-output actives all year round. The smooth flatlock seams and offset shoulder and side seams minimize chafing to keep you comfortable even when wearing a pack all day. Whatever the season or activity, this base layer is designed to keep you comfortable.
