This is the coolest thing I have ever seen.  Have not personally tried it yet, but Jason is usually right on with his reviews.

I purchased mine last spring and I also love it.  I got the 66" model which is a great compromise length for me.  I found the 48" zrest just a little short and the 72" one over kill.  I switched to Neo Air because it's not only lightweight but very compact which I need now that I'm using a lighter & smaller pack.  I have not had too much trouble blowing it up.  When I have any problems I just use some patiences and inflate it a little at a time.  I am concerned, however, that constant inflations using my breath will cause a build up of moisture on the inside and cause problems down the road.
