The fact that these Helly Hansen Ashford Construction Pants are the brand's best-selling knee pad pants should tell you all you need to know about their quality. If that alone doesn't convince you, however, perhaps a rundown of their best features will. These ultra-tough ashford construction pants are engineered from 275 gsm poly-cotton, and reinforced with nylon Cordura in the knee pad and tool pockets. If you're unfamiliar with Cordura's rep, suffice to say these tear-resistant fabrics have been used by the military and are designed for extended outdoor use. If the working day brings you to your knees, at least your trousers are equipped to endure the abrasion.
