The Tough Duck WB03 is a winter work bib built from 12 oz cotton duck with a water-repellent finish and quilted 6 oz polyester insulation. Its standout features are the ankle-to-hip two-way side zippers, which let you put it on over boots, and waterproof seat and knee panels with knee pad pockets. It suits tradespeople, farmers and outdoor workers who need warmth and abrasion resistance more than light weight. Against nylon-shell insulated bibs it breathes better and resists snags, but it is heavier and bulkier, and the cotton duck needs re-treating to keep shedding water. Owners rate it highly, praising the warmth and the side zips in particular.

Owners rate the WB03 highly, with warmth and the full-length side zippers the most repeated praise. A few note the fabric is stiff and heavy out of the bag.
The Tough Duck Insulated Bib Overall (WB03) is made from 12 oz premium cotton duck with a water repellent finish. It has a quilted 6 oz polyester lining for warmth. The overalls are water and wind resistant, and the seat and knees are waterproof.
Brass rivets reinforce the stress points. The front closes with a heavy-duty two-way brass zipper. Two-way zippers run from the ankle to the hip, so the overalls can go on over boots and the pant pockets stay reachable.
The back has an elastic waist, and the shoulder straps adjust. The turned-under hem allows for a 3" extension for tall wearers. The knees have pockets for knee pads, and the chest pocket is loss-proof and holds a cell phone. The overalls are industrial laundry approved.
