The men's Tasman Slipper from UGG is a longtime fan favorite that continuously gets rediscovered generation after generation due to its ultra-lightweight, durable outsole, plush wool lining, and suede uppers. It goes with anything and has an easy slip-on silhouette that will stay timeless forever. The outsole of this product is either a sugarcane EVA outsole, which is a responsible compound using sugarcane foam that allows UGG to reduce dependency on fossil fuels by replacing petroleum-based ethylene, or a Treadlite by UGG™ outsole.
