Be aware that the pocket on back of shorts is a button instead of a zipper, which created three issues for me:
1) Much harder to open/close when on vs. zipper
2) If you do any stretching or warm-up that requires you to lay on back, the button will drive into you
3) I think it's unlikely, to happen, but smaller items (like keys or cards) can still fit through the opening when the snap-button is closed
