SFI Ratings

sfi-foundation-map-200x142.jpgPROFOX is an active member in the SFI Foundation Program. We have been in good standing since our inception and receive all our Certifications and Certified Labels directly from SFI.

Your safety should be the number one reason you invest in a PROFOX driving gear. All of our suits meet or exceed SFI Foundation® minimum requirements.

The SFI Foundation® is a nonprofit organization established to issue standards for the performance and racing industry throughout the United States and the world. SFI tests a long list of products including gloves, driver suits, neck braces, restraint systems, shoes, underwear and window nets.

The SFI specification 3.2A for driver uniforms rates how long a driving suit will offer protection from a second degree burn in an approximation of a fully involved gasoline fire between 1800 and 2100 degrees.

SFI Foundation ratings are measured in calories per unit area per time of exposure. In the chart below shows how you can figure a uniform's approximate protection time until second degree burns by dividing the Thermal Protection Performance (TPP) number by 2.

It's always a good idea to check with your track and sanctioning body for their firesuit requirements.

Suits that do not include a genuine SFI® Certified patch may not provide adequate protection.

If you are ever involved in a fire or obtain holes in your suit, it's time to discard your suit and get a new one. Even the smallest singe is a weak spot in the material and can cause a problem if exposed to fire. Proper maintenance of a driver suit will help extend its useful life and provide you with years of protection. Check our FAQ for washing instructions.
