Product details:

PVC Machine Wash The X-Trapper bib trousers are built tough to last. The front side of the bibs are made of a rip stop Nylpeche fabric, a polyester base coated on each side with PVC. Double layers on the entire front and a triple layer on the chest and knees help these heavy duty bibs stand the test of time. The very durable Cap-coz fabric used on the back of the bibs is made of a thick jersey polyester coated on one side with PVC. Velcro adjustments at the ankles, a side waist adjustment, and adjustable suspenders make these bibs easy to adjust to the perfect fit. Knee-pads can be added to pockets on the inside of the bibs for added comfort.
