iSkin has provided iLounge with further details about its upcoming iSkin Duo for iPod nano case. Much like the Duo for iPod shuffle, the Duo for iPod nano features two layers of silicone protection, reducing all friction points. The included screen protector will sit between the two layers of silicone, keeping it from coming into contact with, and reducing the threat of scratches to, the screen. The wheel protector acts in a similar manner, providing a smooth scrolling action without actually coming into contact with the click wheel itself. The iSkin Duo for iPod nano is expected to ship this month at a price of $29.99.
