The G-FORCE Racing Gear GF565 is the lightest weight and most comfortable SFI-5 suit ever made — period. The shell uses lightweight European shiny Nomex® which is quilted to a specially blended Pro Nomex knit liner. All of the seams are afety stitched for an extra measure of protection. European suits use three layers to meet SFI-5, but we met this standard with only two layers using our Nomex inner liner. These unique features are designed into an incredibly comfortable suit that our competition can only dream about. If you like the slick European look with the best American technology, this is your racing suit.
