Racequip Fire Retardant Underwear Top Racing Base Layer

The Racequip Fire Retardant Underwear Top is an SFI 3.3 rated racing base layer (fire retardant shirt) made to add a layer of heat and flame protection under a driver's fire suit. The knit blends aramid and fire-retardant cotton (FRC). That gives a lightweight garment that performs like Nomex but costs less.

Key Features:

• Exceeds the SFI 3.3 rating, with an SFI tag sewn in
• Lightweight aramid and FRC blended knit fabric
• Soft, supple fabric that dries quickly
• Wicks moisture away from the skin
• Hypoallergenic, so it won't irritate skin
• Flat-sewn seams placed to avoid pressure points
• Long-sleeve design with cuffs at the wrists and a mock turtleneck collar
• Black finish that doesn't show dirt
• Machine washable and holds its shape

Racing base layers are made to fit snugly. They are commonly worn under SFI-rated fire suits, which in many racing series require an SFI 3.3 underlayer. Racequip has made auto racing safety equipment since 1975.
