HOT PRICE!!! Men's Whaleback Waterproof Insulated Jacket - Duluth

*Hell, Michigan, to be exact. A few winters back, it froze solid and clocked a windchill of –27°F. That’s the kind of cold this jacket is made for.

The Whaleback Waterproof Insulated Jacket delivers uncompromising protection when winter hits like a freight train. Inspired by the legendary whaleback steamers that once muscled through wind, sleet and snow on the Great Lakes, this jacket is engineered to take a beating—without slowing you down.

Its 4x-tougher nylon shell is fully windproof, waterproof and breathable, with sealed seams that won’t leak under pressure. Inside, high-efficiency 3M Thinsulate insulation locks in warmth without piling on bulk, keeping you comfortable even when you’re working up a storm. Updated moisture-wicking panels at the back and underarms pull sweat away where heat builds fastest, while pit zips give you instant venting when the pace picks up.

If your jobsite feels more like Lake Superior in January, this is the jacket you want on your back.
