Super.natural Tundra175 Men's Thermal Base Layer Shirt - Jet Black

The Super.natural Tundra175 is a men's long-sleeve thermal base layer shirt engineered for cold-weather performance. Its 175 g/m² fabric blends 50% mulesing-free Merino wool with 50% polyester, delivering lightweight warmth and exceptional temperature regulation.

Advantages

Merino wool naturally resists odors and wicks moisture away from the skin, while the polyester adds durability and quick-drying properties. The result is a breathable, comfortable layer that keeps you dry and fresh during high-output activities. A regular fit and crew neck ensure unrestricted movement and easy layering.
