The Portwest EV402 is an insulated hi-vis trouser for outdoor work in extreme cold and wet weather. A stretch waterproof shell and a lofty, down-like filling keep you warm and dry, while built-in articulation and stretch gussets let you kneel, climb and bend freely.
Zipped ankles with elasticated gussets make it easy to pull the trousers on over work boots. An inner snow gusset at the hem helps keep snow and slush out. Segmented reflective tape keeps you visible in low light.
