I think what you are asking about is a monster tube. It has a hinged opening, so there is no problem getting out after pumping up huge. You can get more info or order one at this URL:

I bought one recently -- works great and very comfortable. Kinda big and heavy tho -- not recommended for walking around and doing stuff. Email me for details.
