The Portwest DX421 DX4 Trade Trousers are made for active trade work that keeps you kneeling, climbing and reaching. Stretch fabric is placed where you move most, and pre-bent knees follow the natural shape of the leg.
A high-rise back waistband with side elastication keeps you covered when bending or crouching. Plenty of dedicated pockets hold your phone, pens, rule and tools, and triple-stitched seams add strength for daily wear.
