You can Velcro your PDA to the right side of the case, so you can use it as a play through case. The back of the case has a belt loop. I don't think that this loop is very convenient because you have to unfasten your belt in order to get the case on and off. The zipper on the SportSuit is heavy duty but still has smooth action. While using the case I never had a problem with the zipper getting jammed.
Hard insert protects the screen.
Thin pocket material inside the case. Belt loop isn't as convenient as a detachable clip. The SportSuit II is a book style zippered case that can be used either as a play through case, slip case, or belt case. The case is basically exactly the same as the SportSuit but is .5 in longer to fit larger PDAs. Hard insert protects the screen.
