The Portwest S491 Sealtex Ultra Hi-Vis Rain Jacket is a lightweight waterproof shell for outdoor work in wet, windy conditions where you need to be clearly seen. Its breathable fabric lets moisture vapour escape, which helps you stay drier from the inside when you are on the move.
Mechanical stretch in the fabric gives you freedom to bend and reach. A pack-away hood, stud adjustable cuffs and a storm-flapped two-way zip let you adjust your protection as the weather changes.
Key features
- Welded seams stop water getting in through the stitching lines
- Breathable, windproof fabric with mechanical stretch moves with you

- Storm flap over the two-way zip keeps out wind and rain, and the zip opens from the bottom for easier access to belt-level kit

- Stud adjustable cuffs close firmly at the wrist to keep rain out
