be incorrect, no, wrong, it is incorrect.
Poly cotton flight suits abound. It is rare a person is allergic or irritated by aramid fiber of nomex but it does occur and those individuals wear poly cotton.
AMC has no problem with the choice of poly cotton. They are cooler in the summer and warmer in winter. Nomex is hot as H in the summer and cold as C in the winter. Personally I won't wear nomex or flight gloves, and yes, I did in the military, because I had to.
Definitely a fan of helmets though, and yes, I dislike them too. They provide protection against head strikes against parts of the aircraft when maneuvering around to get a patient in, etc.
Oh, and yes, I could care less your thoughts on the subjects.
