Case study: Superior Fire Hose Insulated Work Bibs had been a best-seller for years. But the length wasn't quite right, you told us. The leg zippers could be easier to use. And certain wear areas ought to be tougher. So we went to work – and the result is this new improved version! Still the same great bib designed for working outside in blistering cold. Protects you and keeps you warm and comfortable, with Thinsulate® insulation inside tough 11.5-oz. Fire Hose® cotton canvas with our FendOff Finish™ fabric treatment that repels snow, sleet and stains. So what's new? Zipper pass-through pocket for access to your jeans. Longer 2-way leg zips for easier on/off over heavy boots and to allow venting. Better shoulder strap hardware. And reinforced fray-resistant hem and back pockets. Also includes insulated, fleece-lined kangaroo pocket. Zippers under each arm to make the bibs a cinch to put on over thick work clothes. Waterproof double knee patches fight wear and tear and let you kneel in water or slush on the job. Last but not least, there's a back locker loop, because you asked for one.
