Kids Thermal Underwear

Built for active and adventurous children, our kids’ thermal base layers are made for camping, ski holidays, general outdoor play, and even bedtime.

Our essential base layers for kids are designed to keep your little ones feeling super warm and cosy, be it a day playing in the snow or a cuddle session on the sofa. With a super soft, gently ribbed fabric that feels great against the skin, you can rest assured your children are warm, dry, and comfortable. Specifically designed to reduce bulk when layering, getting your kids into these thermals and dressed for the great outdoors is simpler than ever. Using ultra breathable, quick-wicking fabric, kids will love the freedom and comfort that these base layers provide, enabling them to confidently explore even in the harshest, windiest and coldest conditions. Flat seams on the inside prevent chafing and discomfort, meaning no fuss when getting ready and no complaints on longer family days out. With a simple crew-neck top and super comfortable bottoms, these plain yet powerful children's thermals are bound to be a hit with even the fussiest kids.
