The tundra-rated Baffin Litesport Boot is built to bring it on frozen, snow-covered terrain. That starts with Baffin's multi-layer inner boot system, the boot's waterproof base, and built-in gaiters--a winning combination to hold in our body heat and keep out the elements. This pair of winter boots also features Polar Rubber outsoles for the kind of grip we need for our adventures on snowy and icy surfaces.
