Here are the rules most orgs follow:

PROTECTIVE CLOTHING
One-piece firesuits are mandatory. Two-piece suits are not permitted. The suits must cover from the neck to the ankles and to the wrists. The suits must not have any holes, rips, and tears or be worn thin. The suits must also be free from any petroleum-based contaminants. All suits must be made from fire-resistant material with the manufacturer’s fire resistant rating label attached. A minimum of a two-layer firesuit, fire resistant gloves and footwear are very highly recommended. Best In The Desert Racing Association highly recommends that each fire suit be labeled on the upper right chest with the entrant’s full name, blood type, allergies or other important medical information.

My guess is tech will give you trouble without an "SFI" label on the suit. ;)

I doubt a flight suit will get through tech without the SFI label. I know they are Nomex, but they sure are thin, even if legal I don't know that I'd want to depend on it.

One layer fire suits do almost nothing in a fire anyway, so I wouldn't worry any more than if you're wearing the normal Crow/Pyrotech cheapies.

I know ARTS has passed military flight suits through tech at MDR races, not sure I'd just show up with one though. I'd email and get it in writing that they'll pass it, then you've got no worries.
