Someone has already said "organizational" clothing. That is what the N-2/N-3 series heavy weight jackets were. Rarely did they become "personalized" like the other Nylon we have seen. I have seen the reflective tapes, prescribed by a few T.O.'s out there, but that is normally it.
A few of the squadrons have stenciled their respective unit markings on the back, maybe inside but that is all. I have a great N-3B at home, will post pic, that has 3 - 4 names in it hand written them blacked out with a new name hand written in it. Gives it character.
But I have not seen a lot of these N series jackets with a lot of Unit patching.
