The Portwest RT51 is a hi-vis rain trouser for outdoor work in wet, windy weather where you need to stay visible. Its Sealtex Ultra fabric is waterproof, windproof and breathable, so you stay dry from the rain while moisture vapour from your body can escape.
The fabric has mechanical stretch to move with you as you work. A fully elasticated waistband and stud-adjustable hems help the trousers sit securely. Heat-applied HiVistex reflective tape adds visibility in poor light.
