WX3 Flame Resistant Sweatshirt

Flame-Resistant Sweatshirt for Industrial Workwear

The Portwest FR710 WX3 Flame-Resistant Sweatshirt (BKR) is engineered for professionals working in high-heat or hazardous environments where safety and durability are paramount. Combining inherent flame resistance with practical workwear design features, this sweatshirt is ideal for welders, engineers, electricians, and industrial crews who need reliable protection without compromising comfort.

Built-In Protection for Hazardous Jobs

Constructed from Modaflame Knit, this sweatshirt offers inherent flame resistance that won’t wash out, protecting against radiant, convective and contact heat. Its high cotton content ensures superior comfort throughout long shifts, while antistatic properties provide additional safety. Segmented reflective tape increases visibility, making it suitable for varied lighting conditions on site.

Practical Design Meets Workwear Functionality

The FR710 includes a zipped collar for adjustable ventilation, ribbed cuffs and hem for a secure fit, and a comfortable crew-neck silhouette that works with overalls or under outerwear. Its durable construction and thoughtfully engineered features help maintain performance through frequent wear and industrial laundering.
