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

Built for high-output days where temperatures don't cooperate, the Classic All-Season Merino Crew is our go-to base layer for trail runners, hikers, and hunters. Midweight merino regulates body temperature and wicks moisture naturally, so you stay comfortable heating up on a climb or cooling down in a morning stand. Natural odor resistance means you can wear it hard across back-to-back days without it turning on you.

• Midweight merino wool construction regulates temperature in both warm and cold conditions — one base layer that works year-round instead of separate warm- and cold-weather options
• Natural odor resistance handles multi-day trips and back-to-back training days without getting funky — no synthetic base layer can match merino on extended wear
• Crew neck and classic fit work standalone in mild weather or clean underneath a softshell or insulated jacket when temps drop
• Sized S through XXL and available in Burnt Sienna, Mineral Blue, Sable Brown, Nightfall Blue, Fern Green, and Black — earthy tones that work for the woods or the trail
• Built for high-output, variable-condition use — trail running, backpacking, hunting, or any activity where you're heating up and cooling down repeatedly throughout the day
