Matching top and bottom base layers are paired up in a convenient, all-in-one package with the kids' Burton Lightweight Base Layer Set. Stretch, breathable, and quick-drying, this technical head-to-toe combo keeps boys and girls 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, and stretch performance gives junior double-jointed dexterity without bunching or un-tucking.
