Mesa Thermal Shirt - Men's

What Our Gearhead® Experts Are Saying:

"I wore the Mesa Thermal Shirt on a camping trip where the mornings were cold and the afternoons warmed right up, and it handled both without a complaint. The waffle knit has this satisfying weight to it that feels substantial without being stifling, and the henley collar gives it just enough personality to wear it straight into town for dinner."

Cool mornings have a way of slowing everything down, and the Katin Mesa Thermal Shirt is exactly the kind of layer that makes you want to lean into that. Built from a cotton-polyester waffle knit, it brings a comfortable, lived-in warmth that pairs just as naturally with a cup of coffee on the porch as it does with a flannel over the top on a longer trail day.

The three-button henley adds a classic detail that elevates this beyond a basic thermal, giving it a quiet style that works from campsite to main street. The straight hem keeps the silhouette clean and versatile, and the woven Katin flag label at the left side seam is the kind of small, considered touch that signals real craftsmanship without shouting about it.
