How cold does it get in Alaska? So cold it can't even snow. In weather like that, water vapor in the air turns into a solid, ice-crystallized mist called Ice Fog. But no one's standing around marveling – it's just another work day in Alaska. The kind of day where you better suit up in an Alaskan Hardgear® Ice Fog Bibs – the warmest bibs we sell. 700 fill power down warms through extreme cold while the rugged 3.6-oz. nylon shell stays supple in frigid temps. Work ready features include 3M reflective piping (critical in places like Barrow where 7-10 weeks pass without any sun) and Cordura® nylon reinforcements. Hardworking, full-featured design includes adjustable straps, full-length front zipper with outer stormflap, and removable thermal foam inserts in the seat and knees for comfort as you work in extreme weather.
