The G-Force GF125 Series is available as separates (jacket, pants) or a 1-piece driving suit. This jacket is made from award-winning Pyrovatex fabric with GTex construction. GF125 Race Jackets have an impressive 10 TPP rating and carry SFI 3.2A/1 certification. The higher a TPP score, the more time a driver has to evacuate in case of an accident/fire. The pockets of the GF125 are inset or sewn inside to hide seams and provide more usable space with a cleaner design.
