The Portwest RT31 Hi-Vis Rain Traffic Trousers are waterproof overtrousers for rail work and other jobs where you need to stay visible and dry. Side leg zips with a placket let you pull them on over your work trousers or jeans without taking your boots off.
Taped seams and a water-repellent finish keep rain out. Reflective tape helps you stay seen in low light. Pass-through pockets let you reach the clothing underneath.
