Great thread.
My dad flew S-2 Trackers back in the 60's. When I got my orders to flight school, he was so excited that he bought me an custom flight jacket. I was smart enough to put it in my closet and leave it there until I got my wings. It has a really nice liner and it great for really cold days. The issue jacket is so thin that it does not do much except look cool.
Unlike some of you, I really like the jacket that I got from Pensacola. My dad was my hero, and actually getting my own issue flight jacket was a big day for me. Sure, it could be higher quality, but I would never get rid of it. I added a really nice nametag from flightjacket.com, and the large flag on the left shoulder. It looks really good and fits me well.
Of course, my father's leather jacket had a lot more patches than current regs allow us to wear. He was upset that I could not put any cruise/ship patches on my issue jacket like he was able to. I decided to use the jacket that he gave me as a storage device for deployment patches. I probably wear it 5 times a year or less, but it makes the old man happy.
