In my quest to find women's athletic shorts with a lengthy inseam I gave these a whirl.  They're a nice lightweight fabric, knee-length, and best of all have pockets!  (Why the clothing manufacturers of the world think women don't want a place to put their keys while working out is a constant source of confusion and bafflement to me.)

The waistband on these bad boys sits comfortably below the navel, and they don't bind or ride up.

No one is going to look like a fashion plate in these but they're just fine for going to the gym.
