Smartwool Merino 250 Base Layer 3/4 Bottom – Men's

Built for cold-weather output on the trail or in the field, the Merino 250 3/4 Bottom is our pick for guys who need warmth without bulk. 250-weight merino wool regulates temperature as your effort changes and fights odor over long days, while the 3/4 length and chafe-resistant construction keep you moving clean.

• 250-weight merino wool delivers serious warmth without the bulk of heavier synthetics
• Natural temperature regulation keeps you comfortable as effort and conditions shift
• Merino's built-in odor resistance holds up across multi-day hunts, hikes, or cold-weather runs
• 3/4 length sits above the boot cuff — smart for layering under gaiters or bibs
• Low-chafe construction handles high-output movement without the hot spots
