The DX4 Hi-Vis Rain Trousers are waterproof, breathable overtrousers for outdoor work where you need to stay visible and dry. The stretch shell moves with you as you bend, kneel and climb, and the mesh lining adds a light inner layer.
Nine pockets, a hammer loop and knee pad pockets mean you can carry tools and wear knee protection without a separate belt or kit. Side zips at the leg openings make them easier to get on and off.
