Pipelines in Alaska, snow plow routes in Saskatchewan, just getting down the driveway for your newspaper in Minot. For the coldest jobs in the most inhospitable conditions we present the Whaleback Waterproof Parka – our warmest, most weatherproof work jacket ever – named for the innovative and stormproof steamers that once sailed Lake Superior. It's packed with ultra-light, high-efficiency Thinsulate® insulation for warmth all the way down to -25 °F, when you're working up a storm. And tough enough for any job, in tough 6.1-oz. nylon that's nearly 4 times more abrasion resistant than cotton duck work jacket fabric. Packed with all the features you demand in a functional work jacket. Whether it's wind-driven snow or crashing waves of icy water, shake it off with the Whaleback.
