Behold: The protection you'll need when it's colder than Hell. Hell, Michigan, that is. A few winters back it froze over, setting a windchill record of -27°F. There's no better way to stay warm without giving up function than our Whaleback Bib. Named for the whaleback steamers that once shouldered aside wind, sleet and snow on the Great Lakes, these overalls are tough enough for any job without sacrificing the mobility you need. The 4x stronger nylon shell is windproof, waterproof and breathable with leaktight sealed seams. Warm to -15°F, thanks to super-efficient Thinsulate™ insulation throughout. 7 pockets and a drop-seat "bathroom management system" (heh) are practical as, um, hell. If you work where winter's as wild as Lake Superior, you need these overalls.
