For those lung-freezingly cold days when the wind blows straight off the Arctic Circle, you’ve asked for even more protective coverage – and these bibs deliver in spades. Brawny 11.5-oz. Fire Hose® cotton canvas shrugs off abrasion, resists wear and tear. A  FendOff Finish® fabric treatment repels snow, sleet and stains. Thinsulate® insulation adds warmth without bulk. Waterproof reinforced knee patches now extend all the way around the bottom leg hem, so you can kneel in slush without getting soaked. Extra-long 2-way leg zips allow easy on/off over heavy boots. Improved metals sliders secure the comfortable elastic straps right where you want them. Insulated, fleece-lined kangaroo pocket gives hands a quick warm-up, and zippers under each arm make the bibs a cinch to put on over thick work clothes. All in all, they’re the Superior-est Bibs we’ve ever built!
