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

When your day swings from cold morning starts to sweaty midday climbs, this is the bottom layer we reach for first. Merino wool regulates temperature and resists odor naturally, so you stay comfortable across conditions without synthetic funk. Flatlock seams and a slim cut keep everything clean under pants, hunting layers, or bibs.

• Merino wool construction regulates body temperature across changing activity levels — no overheating on the climb, no chill on the descent
• Natural odor resistance handles multi-day trips and back-to-back wear without the stink that builds up in synthetic fabrics
• Slim fit slides cleanly under hiking pants, hunting layers, or ski bibs without bunching, riding up, or adding bulk
• Flatlock seam construction eliminates pressure points and chafe — critical on long days, high-mileage efforts, or all-day hunts
• Available in Black, Iron Heather, and Twilight Blue in sizes S–XXL for a versatile, low-profile base layer you can wear year-round
