coming from a motorsport background where fireproof clothing is mandotory I sometimes wear a flying suit together with the nomex long johns and polo neck in winter , I have seen fire burns in motorsport and i'd rather not have that thank you , I also have a pocket knife on me for this reason ,say you have a prang and the seat belt or harness release jams (it can and does happen ) you can cut and get out , i had mine taped to the roll cage in the racing car, one ot these "life hammers "is also a good idea .
At the end of the day you wear what you want , bone dome got one , tried it in our aircraft , sliding canopy which can be opened in flight , never done it since ,same with a chute we can slide open the canopy , in a PA 28 what chance would you have to get out ??.
However and what ever you wear there is no need to call anyone a pratt ,but if anyone wants to call it to my face when I'm wearing mine come on over LOL
