The G-Force Racing Gear GF-505 multi-layer jacket is lined with a CoolQuilt liner that keeps you dry and cool. The built-in Abzorb-A-Line draws the moisture from the body which keeps your body temperature down. The outer layer is made of a fire retardant cotton. All GF-505 jackets and pants come with Nomex cuffs and arm/leg stripes. Jackets feature a large chest billboard with contrasting piping. All seams are safety stitched to help limit failure in a fire.
The GF-505 have an impressive TPP rating of 26. In order to be classified as SFI 3.2A/5, The SFI Foundation requires a thermal protective performance (TPP) score of 26. Thus GF505 garments exceed the specifications of their intended use, and racers can have confidence in them. Higher TPP ratings allow racers more time to evacuate in the unfortunate event of an accident and/or fire.
