I got a new vest from batninja as I was beginning to outgrow my old one. This is fully weathered and already has slots for the jetpack cut and a spot in the front to put your chest display innards. There are also snaps on the vest where I had my armor attached
This vest is closest to a LARGE size according to his measurements ( I offer these vests in four basic sizes: M (38-40), L (42-44), XL (46-48 ) and XXL (50-52) )
If you are the high side of a medium it could probably work for you or not pushing a large. If you have a 44"+ chest just be reminded it might not fit as well with a flight suit and everything else on. I tried the vest on with just a shirt on and I could get it closed but my movement is restricted and it wasn't comfortable with a flightsuit (I have a 46" chest)
I hope that is straight forward. Make sure it will fit you if you choose to buy.
I would like $85 shipped in the 48 continental USA
