The Carhartt Relaxed Straight Rigby Double-Front Dungaree is an agile, all-season utility work pant engineered to deliver heavy-duty double-knee protection and breathable mobility without the oppressive weight or break-in stiffness of traditional 12-ounce cotton duck. Built for carpenters, electricians, HVAC installers, plumbers, tile setters, and facility maintenance technicians who spend extended hours kneeling on abrasive surfaces or climbing ladders, the chassis is constructed from an 8-ounce tightly woven stretch canvas blend.  This balanced mid-to-lightweight weave resists snags, rough lumber splinters, and sustained surface friction while promoting superior airflow during warm-weather shifts or high-exertion indoor work. Infused with Carhartt Rugged Flex® technology, the canvas flexes and recovers dynamically during deep squats, kneeling, and high steps—providing immediate broken-in comfort straight off the rack.
