Our Medford pant shakes off the rain, not hard work. It's built of durable 100% polyester knit fabric with a PU (polyurethane) coating. Not only waterproof, it's stretchable for easier movement throughout your workday. Reinforced double-knees and seat add durability, and the pant?s elastic waistband with draw cord and barrel-lock adjusters ensures comfort and fit. Built Carhartt strong, the seams are heat sealed and the major seams are also sewn. Upcharge for 3XL+ and Talls.
