Query: UNBELIEVEABLE

I saw that and read the description numerous times. Surely itwas a typo or I was missing something important. Nope. It's made out of NYLON for God's sake. Nylon, the man made fiber that theymake parachutes out of. Then I saw the 5 star review came from someone in SF CA. It's all beginning to make sense now. P.T. Barnum was right!
