The DRIFIRE Men's Drifire FR 4.4 Workshirt is a purpose-built piece of flame-resistant (FR) workwear designed to provide reliable protection in environments where arc flash, flash fire, and other thermal hazards may be present. This shirt meets the requirements of NFPA 70E and offers an arc rating of 4.4 cal/cm², making it suitable for daily use in electrical, utility, and industrial settings. It is constructed from a proprietary blend of cotton and modacrylic fibers, which inherently resists ignition and self-extinguishes when exposed to flames. The fabric is engineered to maintain its FR properties for the life of the garment, even after repeated laundering, ensuring consistent safety performance. Unlike some treated or coated materials, this inherent flame resistance does not wear off, providing long-term value and peace of mind. The workshirt features a classic workwear design with a comfortable, relaxed fit that allows for a full range of motion on the job. Its breathable fabric wicks moisture away from the skin, helping to regulate body temperature during physically demanding tasks in moderate to warm conditions. The shirt includes a reinforced placket, seven-button front, two chest pockets with button closure, and adjustable cuffs, all tailored for practicality and durability. The material has a soft, broken-in feel from the start, reducing break-in time and enhancing wearer comfort across long shifts. The construction emphasizes strong seams and bar-tacked stress points, contributing to the overall longevity of the garment. The shade described is a classic navy, but other color options are available to suit workplace requirements. This workshirt is designed for professionals such as electricians, linemen, oil and gas workers, and maintenance technicians who require flame-resistant clothing (FRC) that combines protection with everyday wearability. Its moderate arc rating makes it appropriate for tasks where secondary arc flash hazards exist, and it layers conveniently under heavier outer FR gear when needed. The affordability of this model positions it as a practical choice for companies outfitting teams or individuals seeking cost-effective FR compliance without sacrificing quality. The shirt is available in a range of sizes from small to 4XL, accommodating diverse body types.

The DRIFIRE Men’s Drifire FR 4.4 Workshirt delivers a balance of thermal protection, comfort, and durability, serving as a functional component of a comprehensive PPE system.
