Unlike other waterproof cases for portable electronic devices, Dry Case lets you retain the use of your iPhone, iPod, etc. Developed by a company that makes waterproof coverings for casts and bandages, Dry Case is essentially a rubber bag with a vacuum pump. Place your gadget into the bag; seal the top by screwing the plastic clamps; pump out the air with the included yellow squeeze ball; strap the Velcro band around your arm. You're ready to get wet and wild, partner! Leave the squeeze ball attached for flotation, or remove it and replace the cap on the one-way valve. Through the clear, flexible membrane, you can tap away on your iPhone, scroll through playlists, or snap digital photos. There's even a headphones input.
