Underwear Bottom Black XXX-Large SFI 3.3

The ZAMP Underwear Bottom Black XXX-Large SFI 3.3 is a fire-retardant racing undergarment designed specifically for use in motorsports where SFI 3.3 certification is required. This base layer is essential for drivers looking for thermal protection in high-performance driving environments, including circle track, drag racing, and road course competitions.

Constructed to meet SFI Foundation 3.3 certification standards, this underwear bottom provides a barrier against fire exposure. The garment is made from inherently flame-resistant materials that char rather than melt or ignite, ensuring passive protection without relying on chemical treatments that can degrade over time.

The XXX-Large sizing in black ensures full-body coverage and thermal consistency beneath your racing suit, minimizing gaps where exposed skin could be vulnerable. This lightweight garment, weighing 0.72 lbs, is designed to manage moisture effectively during extended driving sessions, making it a vital component of any racer's gear.
