The Splash Pack DriPod by Allsop is an air-tight case that will basically waterproof your iPod, headphones or digital camera. I was relieved when I saw it on Chip Chick because you can control your iPod while keeping it nice and sealed without having to remove it from the case. Unlike other hard plastic covers which often make it impossible to use the scroll wheel!
The DriPod also comes with a heat-sealed headphone jack, a lanyard so you can easily carry your gadget and it can be submersed under three meters of water. This size fits iPod nanos and small phones. Larger packs are also available. Priced at $20.
