I looked high and low on the internet for that specific jumpsuit and have found nothing. I have some great images but no one to host them.
I know it has zip-off sleeves and 3 snaps on the front of the belt. It has a zipper in the front and there is a small button near the upper chest region. The chest pockets are zippered as well. The only thing close that I've found was an EMS-Paramedic jumpsuit that had the zip off sleeves but the rest of the suit was incorrect. Perhaps it was a custom job for the show only...
I was thinking about just wearing one of these for Halloween seeing I can't think of anything else at the moment. If anyone finds something, please let me know asap.
Thanks,
Andrew
