I'm very happy with G-Force suit and other products.
I'm a bit old school and believe that Nomex underwear with a lighter suit is more comfortable in hot weather as well as being more protection as long as you choose a size for the outer suit that is big enough to allow air/space. Too tight a fit reduces protection.
I tried a three layer in Texas and almost died of heat exhaustion. Temp and high humidity in the East can be worse than high heat in Texas.
[FONT=Univers][SIZE=1][FONT=Univers][SIZE=1]From GCR: "All suits shall bear an SFI 3.2A/1 or higher certification
label or FIA 1986 Standard or FIA Standard or 8856-2000
homologation label. Underwear of fire resistant material shall
be used, but is optional with suits carrying an FIA Standard
1986 Standard or FIA Standard 8856-2000 label or SFI 3-2A/5
or higher (e.g., /10, /15, /20) certification label."
I would go with Nomex underwear and the lighter suit meeting SFI 3-2A/5 or /10.
Good luck at the Driver's School.
