I'll say this, it is heavy thicker old style material. 100percent Nomex. As to the size, he is 6,5ish and sorta long legs. I measured from just below the collar to the bottom of the leg is 68 inch. From the bottom of collar to the middle of waist band is 25 inch and the inseam is 32 inch. When he was younger this fit him fine now that he is 20lbs older it is tight. If you ain't tall and skinny forget it. Maybe as big as a 36" waist and 44 in. chest. As for price, the suit is $1750 in todays money. The SFI20 boots are $400. with the Nomex undies and neck support, $1500. Or if I sell the SFI 20 boots for $300 then driving suit and everything else is $1200. Back in my TAD NHRA days I bought a suit that was too big for me and had a marine upholstery shop cut it down to fit me. Those days are probably over.
