Eastbay is correct, those are the real authentic shorts. In the description on Eastbay's site it says the only difference between these retail shorts and the team issued ones are that the retail ones have pockets. I bought a pair last year but returned them.
I used to be pretty big into college game shorts, two years ago Nike bumped up the price tag to $80 while moving from tackle-twill to screen-print (aka "heat applique" or whatever dumb buzz words they tried to use) and added pockets to the shorts. They sold so poorly that Nike didn't make any authentic college shorts last year. Glad to see they're back even if they're overpriced.
The $60 replica ones are made of micromesh or whatever as opposed to DriFit and the screen-printed stuff is a little cheaper/flimsier than the $80 authentics. They do not have a rubber-lined waistband either.
Maybe they corrected the authentics though, if you look at these new Zona's on Nike's site and zoom in the CATS on the side looks like tackle-twill.
