Classic All-Season Merino Base Layer Crew – Men's

On high-output days when temperatures swing, the Classic All-Season Merino Base Layer Crew is our go-to base layer for trail runners, hikers, and hunters. Midweight merino regulates temperature and wicks moisture, so you stay comfortable on a climb or in a cold stand, while natural odor resistance keeps it wearable day after day.

• Midweight merino regulates body temperature in both warm and cold conditions, so one layer covers you from early-season hunts to cool-morning trail miles
• Natural moisture wicking pulls sweat off your skin on climbs and keeps you from getting chilled when you stop moving
• Merino's natural odor resistance holds up through back-to-back training days and multi-night trips without turning on you
• Classic-fit crew neck wears alone in mild weather or layers cleanly under a softshell or insulated jacket when temps drop
• Sizes S–XXL in Black, Burnt Sienna, Fern Green, Iron Heather, Mineral Blue, Nightfall Blue, and Sable Brown Mountain
