"Vakaadoo unveiled its iVak cover for the second generation iPod nano on Tuesday. The form-fitting case is 1.7mm thick, and is shaped to match the curves of the nano's body. It includes cut outs for the Click Wheel and ports, and a built-in display protector. The iVak for the 2G iPod nano will be available in mid-January."

I have an iVak case for my iPod 5G and it's got to be the best case I've come across. It fully protects the iPod without adding bulk like other cases tend to do.
