The Portwest T166 PW3 Hi-Vis Rain Jacket (3L) is a high-visibility shell for outdoor work in rain and wind, including rail work in the orange version. Its 3-layer stretch fabric is waterproof, windproof and breathable, so you stay dry and protected through long shifts outside.
It is built for active jobs. The stretch construction and shaped sleeves let you reach, turn and twist freely, and the pockets are designed to be used while wearing a harness.
Key features
- Portwest Extreme 3-layer fabric with mechanical stretch is lightweight and durable, and it moves with you

- Narrow triple storm flap shields the two-way centre front zip for added rain protection
- Detachable helmet-compatible hood with a shaped peak and 3-point adjustment fits over a safety helmet
- Ventilation panels in all pockets help heat and moisture escape when you are working hard
