The Portwest PW351 PW3 Hi-Vis Winter Trousers are an insulated, waterproof bib trouser for outdoor work in cold, wet weather where you need to stay visible. The durable 300D Oxford polyester shell is built for demanding use, with a soft insulated lining for warmth.
Generous storage keeps tools and small items close at hand, and practical details such as side zip leg openings and a boot-shaped hem make them easy to wear on site.
