i ordered it in .6mm thickness to give a little stretch while still being restricting. i figure i can put a piece of paracord on the arm zippers to pull them up, and then i should be able to reach the zipper with my opposite hand to push them back down. if thats the case and its easy enough to reach the zippers while inside it, i might need to get some locking zippers and place the key in the kitchen safe for an extended play session, but we'll see.
the challenge of seeing what i can get myself out of is part of the fun!
