Tough as hell and equipped for any task, the Grindstone Work Bib lets you push hard through the worst weather. It's built with the most durable windproof, water-resistant WINDSTOPPER(R) fabric we've ever engineered-even our lab testing machine couldn't break it. We made it to keep you protected through season after season of working your back 40, hauling lumber, and tuning engines. Double it up with the waterproof Grindstone Work Jacket for complete protection on dawn-to-dark jobs where quitting because of cold, howling winds isn't an option.
