Odlo BL Top Crew Neck Long Sleeve Merino 200 Men's Base Layer T-Shirt, Black, Size L

On a crisp winter morning, a backcountry skier pulls on the Odlo BL Top Crew Neck Long Sleeve Merino 200 before heading into the alpine. The 100% mulesing-free merino wool (200 gsm) immediately feels soft against the skin, while its natural temperature regulation keeps him comfortable during the ascent and descent. Flatlock seams prevent chafing under a backpack, and the athletic fit layers smoothly under a shell. Whether skiing, hiking, or simply navigating a cold city commute, this base layer delivers reliable warmth without overheating.

The crew neck and long sleeves offer full coverage, while the athletic fit eliminates bulk. Mulesing-free sourcing adds ethical peace of mind.
