More than 20,000 hearty souls work the winters up in Prudhoe Bay, where the ice road passes through Coldfoot and Deadhorse. Prudhoe Bay Bibs are as tough and resilient as they are. The lightweight, flat-faced, water-shedding shell borrows technology from bonded fleece athletic gear. But this is no “soft shell“ fabric. It‘s performance workwear made of heavy-duty, abrasion-resistant woven nylon twill with a windproof, highly water-resistant membrane. This shell is bonded to 100% polyester sherpa fleece for comfort and warmth. Guaranteed to deliver extreme wind- and water-resistance, warmth and durability without the weight. Side leg zipper zips to the thighs. Crouch Gusset® gives you ultimate freedom to crouch and move, and there's a knee-pad insert option when things get down and dirty. Includes storm flap and snaps to seal out snow, 8 pockets including hammer and utility pockets, flat utility loop, boot scuffs at leg openings, metal shank buttons and riveted construction throughout.
