Merino 250 Base Layer Bottom – Women's

Built for cold-weather layering, the Merino 250 Base Layer Bottom is our top pick for women who need reliable warmth without the bulk. Pure merino wool regulates temperature naturally and fights odor even on multi-day trips. An updated fit keeps it locked in place so it moves with you under whatever you stack on top.

• 100% merino wool construction delivers natural, breathable warmth in cold conditions
• Built-in odor resistance handles multi-day wear without washing
• Updated fit sits close to the body without binding or bunching under layers
• Best for cold-weather base layering during trail runs, hikes, or hunts
• Merino regulates temperature across effort levels — warm when you need it, not suffocating when you heat up
