SFI 3.3 Nomex Long Sleeved Shirt

Stay safe and comfortable with our SFI 3.3 Nomex long sleeved shirt, designed for superior fire resistance and durability as part of your racing undergarment system. This long sleeve top provides crucial thermal protection for your upper body, arms, and neck when worn under an SFI-rated race suit, helping provide extra seconds of protection in a fire situation. Lightweight and breathable construction allows heat and moisture to escape while maintaining flame-resistant performance, so you stay focused through long stints and hot race days.​

Perfect for racers and professionals who demand top-notch protection, this shirt is compliant with SFI 3.3 safety standards for underclothing, which require a minimum TPP rating of 6.0 cal/cm² for fire exposure. The long sleeve design features cuffs at the wrists and a mock turtleneck collar that extends snugly to the neck, reducing gaps and ensuring proper overlap with your race suit, gloves, and head sock. Made from aramid fiber blend (similar to Nomex®) that is inherently fire resistant, not chemically treated—ensuring long-lasting protection that won’t wash out over time. Pair it with SFI 3.3 Nomex pants, head sock, and socks to complete a comprehensive fire-resistant base layer system that enhances the performance of any SFI 3.2A-rated suit.
