Women's are Size 6: 28.5 inches, 18–20 oz.

I bought this ball from Costco last year for the same price. Probably about as good as it gets for the price.

Real question is how does this stack up to an Evolution?

Probably doesn't hold a candle to the Evolution, cause that's strictly an indoor ball only.

Sounds too good to be true. I'll pay 4x the price for this one, I'm sure this is 'rare' collector's item.

Is it very good for one that can be sued outdoors? For my indoor one I am about to have to shell out $125 for an evo nxt because I only want official game approved balls for indoors. My stupid wilson solution started leaking air constantly and now i got my needle stuck in it.
