Therman Thermal Shirt - Men's

What Our Gearhead® Experts Are Saying:

"I’ve been using this as a base layer on cooler mornings, and it’s just right—not too heavy, but enough to take the edge off. It’s soft and doesn’t feel restrictive under a jacket."

Cool mornings and shifting temperatures call for a layer that’s easy to trust, and the Therman Thermal Shirt from Katin fits right into that role. It’s the piece we reach for when we need just enough warmth to stay comfortable without overdoing it.

The cotton-poly blend creates a soft, breathable feel that works well against the skin or layered under outerwear. Its midweight thermal construction holds warmth without adding bulk, making it easy to wear throughout the day as conditions change. Ribbed cuffs help keep the fit secure, while the clean silhouette keeps it versatile across different settings.
