These flame resistant waterproof trousers are for wet conditions where you also need extra warmth. The breathable shell keeps rain out and lets moisture escape, while the flame resistant cotton lining adds a warm layer next to the skin.
Elasticated FR braces hold the trousers in place as you bend and stretch. A raised back adds warmth and covers the lower back, and sewn-on reflective tape helps you stay visible.
