Shield yourself from the unexpected with the Portwest FR503 WX3 Black Flame Retardant Overalls. Engineered for maximum protection, exceptional comfort, and modern aesthetics, these coveralls are the perfect choice for professionals working in high-heat, welding, arc flash, and molten metal environments.

Built with cutting-edge Modaflame® 280gsm fabric, these coveralls offer inherent flame resistance that won’t wash away, ensuring long-lasting safety even after countless washes. But safety doesn’t come at the cost of comfort. The innovative WX3™ technical stretch fabric allows for superior freedom of movement and flexibility, while the pre-bent sleeves and adjustable features guarantee a snug and comfortable fit.
