Nomex gear.
I too am interested but with a different twist.
I've looked at a bunch of sites offering Nomex flight suites and I don't want one that looks like military or police. I'm not military and feel really uncomfortable in military type gear. My air force son even offered but again, I don't feel right.
We use fire resistant uniforms in the oil refinery arena but it isn't very suitable to flying in: heavy, bulky, hot, etc.
So, if anyone has a source that doesn't look military and is suitable to fly in, please let me know. I will be ready for first flight in about 60 days so I need to start looking.
