I believe that it is some kind of field gear that is already in the escape pods.
Could be, but if it's already in the escape pod, how does the escape pod know to have the right uniform for the right person? (No good for a Lt. Arex or Keenser type, for example.) It looks like Scotty escaped in a torpedo tube, but so many others were in escape pods, and you'd think a few would at least have had time to change into whatever kind of "away team" or "survival" gear that is.
The entire Franklin is a mystery, really. Why's it there? What happened to its crew? What's it's story? Did it land or crash? Was it being kept a secret by some locals? Have they been maintaining it, or is it a relic? Why? How is it still space-worthy? Actually, it's a touchy subject that will need some good answers, because it's damn convenient to have it there if it's their method of escape.
