Durable, flexible with room to move, the Builders Carpenter Stretch Pants are a true workwear staple. They’re built with our custom stretch canvas made from REPREVE® recycled polyester derived from plastic bottles. Reinforced knees will stand the test of time, and a bottom vent will prevent any dirt collecting if the first layer does wear through. Keep your phone separate in its own pocket on the left thigh, easily accessible from a seated position. Finished with a water-resistant coating and reinforced seams.
