Introducing the Portwest S781 Bizflame Rain Lined Hi-Vis Antistatic FR Trousers, a premium choice for professionals seeking ultimate protection and comfort in adverse weather conditions. These waterproof trousers are specifically designed for wet environments where additional warmth is paramount. Featuring elasticated FR braces and a raised back, they ensure the trousers stay securely in place during rigorous activities, providing extra warmth and protection. The flame-resistant treated waterproof fabric not only prevents water penetration but also offers safety against fire hazards, making it an ideal garment for challenging work settings.

The trousers are lined with FR cotton for added warmth and comfort, and come equipped with zipped ankles for easy fitting over work boots. The back waist buggy offers added protection, while the ergonomic quick-release buckle and adjustable straps ensure a secure and comfortable fit. The trousers are enhanced with premium sew-on flame-resistant reflective tape for increased visibility, and the breathable fabric with taped seams keeps the wearer cool, dry, and comfortable. Fully elasticated waistband, CE certification, and compliance with RIS 3279-TOM for the rail industry (orange only) underscore the trousers' high safety standards. Whether facing rain, fire, or static, the Portwest S781 trousers are designed to keep you protected and comfortable.
