This bib is the real deal–-trust us. If you work in wet environments, you should give the Surrey Bib a try. There's nothing worse than being wet and cold when there's still lot's of work to do, but this bib eliminates that problem. The .50 mm, polyester-backed PVC (polyvinyl chloride) fabric will stand up under the toughest abuse without letting in a drop of water, keeping you warm and dry. The reinforced knee features pockets for optional knee pads, and the electronically welded seams will keep them and the rest of the bib in top condition. The adjustable inseams allow you to customize the leg to a perfect length.
