The Carhartt Work-Flex pant is highly durable and lightweight, perfect for working in those warmer temperatures. This pant is made from 100% polyester knit fabric with a polyurethane (PU) coating with heat-sealed seams. The heat-sealed seams are what make this pant waterproof and wind-resistant for wet or dry conditions. Reinforced double knees and seat with more stretch to improve range of motion and durability. Carhartt has given the work-flex pant snap-adjustable leg openings, adjustable inseam length with cut off seams and an elastic waistband with draw cord for the best fit.
