The Portwest FR427 PW3 Modaflame Rain+ Hi-Vis FR Winter Holster Trousers are built for cold, wet work where heat, flame and electric arc are all hazards. They pair inherent flame resistance and high-visibility protection with a waterproof, padded build.
The two-tone design carries segmented reflective tape, and the trousers are suitable for wear in ATEX environments. Nine pockets, including zip-off holsters and two-tier knee pad pockets, keep tools and protection where you need them.
Key features
- Inherent flame resistance stays with the fabric through washing

- Fully lined and padded with FR cotton lining and FR filling to trap heat and keep you warm
- Taped seams for additional protection
- Heat-applied segmented reflective tape for added visibility
- Zip-off holster pockets that can be swapped between sides, so you choose where your tools sit
- Two-tier, bottom-loading knee pad pockets give two positioning options for the pads
- Cargo, side and rule pockets, with a side elastic waist and concealed fly zip
- Non-magnetic, nickel and ferrous free, so the trousers are metal detector friendly
