The DryCASE was created by DryCORP, makers of waterproof body protection products for the medical industry. DryCORP's motto is: "Air Tight. Fits Right" That can also be said of the DryCASE, a clear case with a vacuum seal that protects anything you put in it. As you can see from the photo below, the DryCASE is mainly designed to hold MP3 players. It can also carry, cell phones, cameras and other valuables. At a retail price of $39.95, it's a good investment if you're playing in or near the water.
