These hi-vis winter trousers are built for multi-risk environments where you need protection from heat and flame, cold and wet weather at the same time. The flame resistant waterproof shell is padded and fully lined, so you stay warm and dry through long outdoor shifts.
The fully elasticated waist lets you pull them on over your everyday clothes. Side zip leg openings make dressing easier when you are already wearing boots. A reflective standards label on the thigh makes the protection level easy to identify on site.
