Underwear Bottom Black X-Large SFI-1

The PYROTECT Underwear Bottom Black X-Large SFI-1 is a fire-retardant base layer designed specifically for drivers, pit crew, and motorsports professionals who require reliable thermal protection in high-risk environments. This garment is engineered to provide essential flame resistance during competition and track testing.

Constructed from Nomex material and certified to SFI 3.3/1 standards, the underwear bottom resists ignition and limits heat transfer in direct flame exposure. The inherent flame resistance of Nomex fiber ensures breathability and comfort during extended wear under suits and driving gear, making it an ideal choice for those in demanding situations.

This X-Large size accommodates layering versatility while remaining fitted enough for proper heat dissipation. Pairing with matching fire-retardant upper layers and SFI-approved outer suits creates a complete fire-resistant ensemble that meets the requirements for professional racing, providing confidence for those in high-stakes environments.
