Long Sleeve Knit Shirt M edium

The Long Sleeve Knit Shirt Medium from CROW Safety Gear is a specialized fire-retardant underwear top designed for professional racers, rescue personnel, and anyone requiring thermal protection in high-heat environments. This SFI 3.3-certified garment serves as a critical base layer beneath racing suits, firefighting gear, or industrial protective equipment. The turtle neck design provides extended coverage for the neck and lower face, an essential feature for occupations where exposure to flame or extreme heat is an occupational hazard.

Constructed from fire-retardant cotton, the Long Sleeve Knit Shirt offers reliable thermal barrier protection while maintaining breathability and comfort during extended wear. The knit construction provides natural stretch and flexibility, allowing unrestricted movement during high-intensity activities. Fire-retardant cotton fabric resists ignition and limits flame spread, meeting stringent SFI 3.3 standards—the recognized benchmark for motorsports and emergency response apparel. The black colorway offers professional appearance while minimizing visible wear and discoloration over time.

This medium-sized shirt is ideal for racers preparing for sanctioned competitions, firefighters requiring compliant base layers, and industrial workers in thermal hazard zones. The Long Sleeve Knit Shirt pairs seamlessly as an underlayer beneath racing suits, nomex outer garments, or standard protective uniforms. Its lightweight profile—just 1 pound—ensures minimal bulk while maximizing protection, making it suitable for environments where layering must remain compact without sacrificing safety standards.
