Don’t let a rainy day keep you from listening to your music. These waterproof bags will keep your iPod dry with a three-roll closure system and built-in watertight audio jack with 10"" internal cord. They’ll also float if accidentally submerged. Made of tough, lightweight ripstop nylon with a clear vinyl window so you can see what’s going on and work most controls. The Large is basically the same as the Small, except it’s taller for larger units, is made of vinyl and has a foam padded back for extra protection. Also has an accessory clip. Made primarily for mp3 players, but also works for radios, walkie talkies, gps units, etc. “I’m ridin’ in the rain… just ridin’ in the rain… what a glorious feeeellllinn’ - I’m hap-py a-gain.” Glub, glub, glub... Small: 7""×4.5"". Large: 9""×4.25"".
