I've been chasing down an SG-1 offworld jacked for the longest time.
The only thing I've found that comes even remotely close are the jackets from 'Children of the Gods'; the shiny material. Rather than buying an actual Air Force issue jacket, there's the option of buying one from Hello Cosplay or CosplaySky. CosplaySky's jacket is very show-accurate, but I've heard...not so good things about their craftsmanship. Hello Cosplay, on the other hand, is great when it comes to craftsmanship but their jacket is..not very show-accurate. But it comes with the patches whereas the one from CosplaySky doesn't.
To those of you who own SG-1 jackets, how did you obtain them? Did you make them yourself? Custom-made from a cosplay site?
