1. This is an original triple woven jumpable medical backpack from the Vietnam , Grenada, and Panama Era. It was primarily used by a JSOC - Joint Special Operations Command Medic. It is a Jumpable Medical Backpack that was in issue from post Vietnam, and Grenada Era. I would have to say early 80's from looking at it. It is in good condition for it's age. The zippers are in really good condition, and zip up and down fine. It has some minor flaws, and wear. It has a few places that were torn on it, but They were sewn over twice. The places on the front, and on the inside of the pockets were sewn with O.D.Green sewing thread, then sewn back over with black thread. So the sews are pretty clean, as shown in the pictures. These are pretty sought after considering that they don't make them anymore. It comes from a smoke - free, pet - free home.
