Portwest DX4 Hi-Vis Rain Trouser – Premium Stretch Waterproof Overtrousers with Class 2 Visibility
The Portwest DX4 Hi-Vis Rain Trouser delivers outstanding wet weather protection combined with the innovative stretch technology that defines the DX4 collection. Engineered using Portwest Extreme Waterproof and Breathable fabric, these overtrousers provide reliable defence against rain, wind and adverse conditions while maintaining exceptional comfort and freedom of movement throughout your working day.
Featuring 4-way dynamic stretch fabric, the DX4 Rain Trouser offers unrestricted movement for active work environments. The lightweight PU membrane construction ensures waterproof protection without the bulk, making these trousers ideal for layering over work clothing. Fully taped seams prevent water penetration at every stitch point, while the PFAS-free Texpel Splash Eco finish causes water to bead away from the fabric surface.
The contemporary design incorporates HiVisTex Pro segmented reflective tape for enhanced 360-degree visibility in low-light conditions. Certified to EN ISO 20471 Class 2, these trousers meet the stringent requirements for high-visibility safety workwear. The EN 343 waterproof certification confirms protection against rain and wind, making them suitable for outdoor workers across multiple industries.
Practical features include an elasticated waistband with adjustable drawcord for a secure fit, zipped side leg openings for easy on/off over boots, and secure zip pockets for essential storage. The adjustable hem allows customisation of leg length and helps seal out water ingress. Whether you're working on highways, construction sites, railways or utilities, the Portwest DX4 Hi-Vis Rain Trouser combines safety certification with DX4 innovation for professional wet weather performance.

Frequently Asked Questions
Q: What makes the DX4 Rain Trouser different from standard hi-vis overtrousers?
A: The DX4 Rain Trouser features Portwest's innovative 4-way dynamic stretch fabric, offering unrestricted movement that traditional rain trousers cannot match. Combined with lightweight breathable construction, HiVisTex Pro segmented reflective tape, and the eco-friendly Texpel Splash Eco finish, these trousers deliver premium performance with modern sustainability credentials.
Q: Are these trousers suitable for wearing over work boots?
A: Yes, the DX4 Rain Trouser is specifically designed for layering. Full-length side zips allow you to put on or remove the trousers without removing your boots. The adjustable hem can be tightened around footwear to prevent water ingress while maintaining easy movement.
Q: What hi-vis class rating do these trousers achieve?
A: The Portwest DX4 Hi-Vis Rain Trouser is certified to EN ISO 20471 Class 2, providing the necessary high-visibility protection for most outdoor and roadside work environments. When paired with a compatible Class 2 or Class 3 hi-vis jacket, the combination can achieve enhanced visibility coverage.
Q: How waterproof are these trousers?
A: The trousers are certified to EN 343 for waterproof and windproof protection. The Portwest Extreme Waterproof fabric with PU membrane provides reliable water resistance, while fully taped seams prevent water penetration at every stitch point. The Texpel Splash Eco finish adds an additional layer of water repellency, causing water to bead and roll off.
Q: How should I care for these rain trousers?
A: Machine wash at 40°C with similar colours using a gentle detergent. Avoid fabric softeners as they can affect the water-repellent finish. Do not tumble dry, bleach or iron.
