I bought one a few weeks ago at my LBS, but made the mistake of not getting one for the rest of my family (!).

I'm home in Chicago now, and went to FIVE places yesterday trying to find them-- they were all sold out!!

my mom and i drove down to the Nike outlet store today, where they just ordered 8,000 more (they've sold 15,000 so far!)

I have seen so many people wearing them! it's so cool!! a friend of mine went to a "plain-clothes" play at UM, and all of the actors were wearing them. the salesguy at Eddie Bauer yesterday told me his mom wears one too
