The North Face Kids' THERMOBALL™ Pull-On WP Winter Boots are lightweight, waterproof boots designed to keep young explorers warm, dry, and protected through cold winter days. The upper is made with 100% recycled P.E.T. ripstop and features a non-PFC DWR finish for added water repellency. A waterproof DRYVENT™ membrane helps keep moisture out, while THERMOBALL™ insulation made with 100% recycled polyester provides warmth even when wet. Inside, a low pile fleece lining adds comfort, and a synthetic mudguard helps protect against the elements. An adjustable collar bungee creates a secure fit and helps keep snow out, while branded webbing pull loops on both sides make the boots easy to put on. Finished with a rubber outsole for increased traction, these boots are ready for cold weather adventures.
