i have known "hyper stereotyped caricatures of italians".(yes we actually had them in the parachute industry. at a company which no longer exists,due to the death of its owner, that made altimeters).the potrayal is not THAT far off.
nice thought. BUT fire resistant fabrics such as NOMEX are VERY expensive(well over $20 a yard)imagine what you would end up paying for a jumpsuit made of it.
