PRODUCT DETAILS
Fortiflame® Layer I fire-resistant base layer boxer with fly features a premium jersey knit blend of modacrylic, rayon, and nylon yarns engineered for maximum protection and comfort. This inherently flame-resistant fabric meets ASTM D 6413-11 standards with zero after-flame or melt/drip characteristics and is HRC1 certified per NFPA 70E requirements for electrical arc protection. Despite meeting these demanding safety standards, the material remains soft and breathable against skin. Advanced moisture-wicking technology keeps you dry and comfortable during extended wear, while integrated antimicrobial treatment actively resists odor buildup. Flat seam construction eliminates chafing from tactical gear and equipment. Made in the USA and BERRY Compliant. Ideal for first responders, military personnel, and workers in high-risk electrical environments requiring certified flame-resistant undergarments.
