Wolverine Big BisonWhen the weather gets rough, you need a boot that does more than add extra layering for warmth. For all-around protection from the elements, the Big Bison from Wolverine won’t leave you out in the cold. Starting with split suede and Cordura nylon that covers the all-terrain-ready exterior, you can move quickly and powerfully through any ground conditions with a durable rubber lug outsole. Inside the boot, a breathable GORE-TEX waterproof membrane and Thinsulate Ultra insulation provides warmth and keeps moisture at bay. The longer you wear them, you’ll realize no weather report is too extreme for a day on the job with Big Bison.
