Matching top and bottom base layers are paired up in a convenient, all-in-one package with the kids' Burton Lightweight Base Layer Set. Designed to stretch, breathe, and dry quick, this technical head-to-toe combo keeps kids warm and dry whether they're on the mountain or just on the couch. Softlock seams and anti-pilling properties mean long-lasting chafe-free comfort, while stretch performance gives junior double jointed dexterity without bunching or untucking.
