Born in the wilds of the Canadian north, winter boots don’t come any warmer than this. In fact, more folks have stood at the north and south poles in Baffin® Impact boots than in any other. The Polar Prove® technology is rated to perform down to -100ºC/-148ºF thanks to a comprehensive, multi-layer removable liner. Not only is it incredibly warm, but it's actually built to hug your foot like no standard felt pack boot liner can, so you can walk comfortably for hours. Ideal for all day on your snow machine, running equipment on the jobsite or working a pipeline project in the Dakotas, Baffin® Impact boots keep feet warm and dry in even the harshest conditions.
