Classic Thermal Merino Base Layer Bottom – Men's

When cold weather hits the trail or the deer stand, this is the base layer bottom we pull out first. Pure merino wool regulates temperature and fights odor naturally — no synthetics required — while thermal-weight interlock knit keeps you warm without stiffness. Flatlock seams and a slim fit mean it disappears cleanly under hunting bibs or ski outerwear.

• 100% merino wool delivers natural warmth, breathability, and odor resistance through long days in cold conditions
• Thermal-weight interlock knit construction insulates in the cold without the bulk or rigidity of heavier fabrics
• Flatlock seam construction eliminates pressure points and chafing during high-output movement on technical terrain
• Slim fit layers cleanly under hunting bibs, trail pants, or ski outerwear without bunching, riding up, or adding bulk
• Available in Black, Charcoal Heather, Deep Navy, and Winter Moss Heather in sizes S–XXL
