PW3 Flame Resistant Class 1 Sweatshirt

Flame-Resistant High-Vis Workwear Sweatshirt

The Portwest FR716 PW3 Flame Resistant Class 1 Sweatshirt is engineered for professionals facing heat, flame and arc hazards on the job. Combining high-visibility performance with inherent flame resistance, this crew-neck workwear sweater is ideal for industries such as oil & gas, welding, utilities, and heavy manufacturing. It delivers essential protection without sacrificing comfort or durability.

Advanced Protection for Hazardous Work Environments

Designed with safety at its core, the FR716 uses Modaflame knit fabric that offers inherent flame resistance that won’t diminish with washing. It protects against radiant, convective and contact heat as well as electric arc dangers, while maintaining breathability and comfort — even during long shifts. With Class 1 high-visibility certification, this sweatshirt enhances wearer visibility in low-light conditions for added safety.

Practical & Comfortable Workwear Design

Built for everyday industrial use, the FR716 features ribbed collar, cuffs and hem to help maintain fit and shape. The crew-neck style ensures unrestricted movement, and the high cotton content gives superior comfort compared to standard protective outerwear. Anti-static properties and UPF 40+ UV protection further enhance its performance on site.
