That's funny! Because when I think about it, sweaty hands are far worse than sweaty legs. People wipe their faces and noses with their hands, and scratch, and other stuff. I'd rather deal with the outside of someone's leg. (Not that it's an either/or proposition; you have to deal with both the leg and the hand. But the hand is worse than the leg, to me.)
And for me, it takes far less time to reach under my shorts than to dig in my pocket.
To each his (her) own ....
Anyway, have you tried some of the non-tennis athletic catalogs, like Athleta or Title 9 or REI? THey have nice stuff, and a decent variety. I also buy shorts at Target, for cheap knockoffs. But they probably don't have pockets.
