The North Face ThermoBall Traction Mule V in Phantom delivers iconic comfort reimagined for everyday life. Originally designed for base camp recovery, these slip-ons are lightweight, packable, and built for warmth. The upper is crafted from 100% recycled PET ripstop with a non-PFC DWR finish for water repellency, while ThermoBall™ insulation made from 100% recycled polyester ensures cozy warmth—even when wet. Inside, an Oso fleece collar lining adds plush comfort, and the collapsible heel with elastic side panels makes on-and-off wear effortless. Finished with an outsole made from up to 20% recycled rubber, these mules combine sustainability, durability, and all-day ease.
