The Portwest DX408 DX4 Back Support Work Trousers are built for physical work that keeps you bending, kneeling and lifting. An integrated back support reinforces the spine and supports the lower abdomen and back. Its belt adjusts for comfort and can be worn under or over your clothing.
Stretch fabric is placed where you move most, so the trousers follow you through every working position. A high back waistband with side elastication keeps your lower back covered. Plenty of pockets, including zipped thigh pockets, keep your phone, pens and tools secure.
