Only when you are starting to run out of ideas do you come to the absurd conclusion that it would be fun to put somebody in a PVC rest sack and then put that rest sack inside a vacuum bed and suck the air out. Well, it made for an interesting picture. It is the perfect solution for somebody who loves the feel of PVC, but wants the restrictiveness only provided by a latex vacuum bed. Overall, it was a novel idea. Don't try this one at home, folks!
