Waterproof ThermoBall™ mules with Vibram® XS Trek outsole
Inspired by our legendary Base Camp Duffel, our new waterproof mules are designed for wet and windy adventures. The seam-sealed construction keeps the rain out, while ThermoBall™ provides insulation that's as warm and cosy as down but stays toasty, even when wet. Plus, our high-performing Vibram® XS Trek rubber outsole provides the optimal balance of traction and durability to keep your footing firm.
