Love this for my CAMPING  TRAVEL PILLOW!
Stows small and best pillow yet for my neck and back!  Just blow some air into the hole to fill and WOW!!! I LOVE IT!!
When you are done just smooth the air out empty and go! Just took it on a trip. Works well without water to. (Just as travel pillow) and when I'm home my dog loves it! 
I need to buy another!! Normally I have neck pain from regular pillows, love this its like sleeping on air, literally!
