These DX4 hi-vis trousers are built for active work where you need to be seen and need your tools close at hand. Stretch fabrics are placed where you bend, kneel and climb, so the trousers move with you through the working day.
Holster pockets zip off when you need a lighter load. A high-rise back waistband keeps you covered when you crouch or reach. A stain-resistant finish helps the trousers shrug off grime and water on site.

- Texpel Stain Eco finish repels grime and water to help keep the trousers looking clean
