Long Sleeve Knit Shirt X -Large

The Long Sleeve Knit Shirt X-Large by CROW Safety Gear is a professional-grade fire-retardant underwear top engineered for drivers, pit crew, and motorsports professionals who demand maximum thermal protection. This turtle neck design provides full neck coverage—a critical safety feature in high-heat environments where exposed skin poses burn risk. Built to SFI 3.3 certification standards, this garment meets the rigorous safety requirements of sanctioning bodies across motorsports racing and professional automotive work.

Constructed from fire-retardant cotton blend fabric, the Long Sleeve Knit Shirt X-Large offers superior thermal barrier properties while maintaining breathability during extended wear in cockpit or shop environments. The knit construction allows controlled stretch and movement without compromising structural integrity under heat stress. Cotton-based fire-retardant fibers work by charring rather than melting, which prevents material from fusing to skin in extreme-temperature scenarios—a fundamental advantage over synthetic alternatives in motorsports safety protocols.

This X-Large sizing is ideal for drivers layering under racing suits, mechanics wearing fireproof apparel during fabrication work, or pit crew members exposed to fuel and engine heat. The long sleeve and turtle neck design work in concert with outer fire suits to create a complete thermal protection system. SFI 3.3 certification ensures compliance with competition rules and workplace safety standards, making this base layer an essential component for anyone serious about motorsports or high-temperature industrial safety.
