You don’t quit no matter how grueling the job. Your work pants should be every bit as unrelenting. Meet DuluthFlex® Fire Hose® HD – a high-tech wonder fabric that withstands abrasion 4X better than your tried-and-true cotton canvas work pants. Better yet, it has more than double the tensile strength and rip resistance of highly durable original DuluthFlex Fire Hose fabric. Yet for all its ruggedness, DuluthFlex Fire Hose HD is remarkably wearable thanks to the work-friendly 10-oz. weight and remarkable built-in stretch. Naturally, these pants are engineered with all the functionality you expect from Duluth, including a moisture-shedding DWR fabric finish, articulated knees and a roomier Crouch Gusset® for comfort in those tender places where other pants pinch. Last, but far from least, they’re triple-stiched and outfitted with 8 practical pockets. DuluthFlex Fire Hose HD – our toughest work pants for the trades’ toughest men.
