Classic Thermal Merino Base Layer Bottom – Men's

On cold mornings in the stand or long days on the trail, the Classic Thermal Merino is our go-to base layer bottom for hunters and hikers who need warmth without bulk. Pure merino means natural temperature regulation and odor resistance, while the slim interlock knit and flatlock seams keep you moving comfortably under pants or bibs.

• Thermal-weight interlock knit traps warmth for cold stand sits and winter hikes without the stiffness of heavier fabrics
• 100% merino wool regulates temperature naturally and fights odor, so it holds up over multi-day trips with no synthetics
• Flatlock seams eliminate pressure points and chafing under a pack, harness, or bibs on high-output days
• Slim fit disappears under hunting pants, trail pants, or ski bibs without bunching or riding up
• Four colors (Black, Charcoal Heather, Deep Navy, Winter Moss Heather) in sizes S–XXL
