These GF105 driving suits meet the SFI 3.2A/1 rating and carry a TPP rating of 11. These suits combine entry-level safety with top-of-the-line quality. They're made from an industry-changing, fire-retardant cloth treated with our new HydroFiber molecular treatment process. These suits are accented with standard epaulets, a belt with loops, arm and leg stripes, a pleated back, Nomex cuffs, and a large white chest billboard with contrasting piping. All seams are safety-stitched to help limit failure in a fire.
