Grantwood Technology has released the tuneband armband for the iPod nano 4G. The product is designed to securely hold the iPod while exercising, with a flexible band that is claimed to fit a wide range of arm sizes. A silicone skin holds the device without interfering with controls or ports. The screen can also be protected with an included cut-and-peel film. The tuneband is also compatible with the Nike+iPod Sport Kit.

A variety of colors are available including clear, gray, black, navy blue, purple, teal, green, red and pink. The tunebands are available now from the company for $13.
