Kid's Thermal Underwear

We want kids to have thermal underwear that’s just as high-quality as what we adults wear. We’ve made it from the same material, with the same quality and design, so you and your little ones can coordinate perfectly.

Our merino blend thermal underwear combines the best of both worlds—the natural properties of wool and the functionality of modern synthetic fibers. The result is underwear that’s comfortable, doesn’t itch, wicks away sweat effectively, retains its shape, and performs as it should when you’re on the move.

Thanks to its thoughtful composition, it can be thinner yet more effective than many thicker functional thermal garments. And it can handle more than you’d expect—from winter mountains to fall runs, all-day travel, playing on the playground, or even a ski touring trip or chilly morning walks to school.
