KEEN REVEL IV MID POLAR BLACK/HARBOR GRAY

The agility of a light hiker with the warmth of a down jacket. With 200g of insulation, heat-trapping materials underfoot, and exceptional grip on snow and ice.

Generous space across your forefoot for toes to spread out. Foot is roomy and comfortable.

PFAS-free waterproof, breathable membrane that lets vapor out without letting water in.

Recycled P.E.T. plastic fibers create lightweight insulation in varying weights for warmth that has less impact on the environment.

A thermal foil barrier keeps the cold out and the heat in by harnessing radiant heat.

Three layers of heat-trapping materials underfoot.

Microscopic shards in the outsole create a “micro cleat” effect for better grip on snow, ice and wet or oily surfaces.

No Stubbed Toes. Our durable rubber toe bumper helps keep toes protected from rocks and debris.

Environmentally preferred premium leather from LWG-certified tannery.

Eco Anti-Odor for natural, pesticide-free odor control.
