The Smartphone Experts ActiveLife Workout Case keeps your Treo sweatfree.

This neoprene case has an opening at the top, where you slide-in your Treo and secure it in place with its velcro latch. There's an opening at the bottom so your headphone jack is readily accessible.

A clear plastic covering offers protection for your keyboard and screen.

The sides of the case are rubberized for easy gripping.

And it comes with a velcro armband that keeps it securely fastened, no slippage, no matter how much you bounce around.
