TuneBand for iPod nano 5th Generation (Model A1320, Rear Camera), Premium Armband, Compatible with Nike+iPod
I purchased this based on the reviews and have nothing but positive things to say about it.  Fits the 5th generation perfectly, and I still have access to all the features of my ipod.  This is perfect for the gym, working around the house, or anytime you want hands free listening.  The velcro is really strong, and the cover itself very flexible and can easily be cleaned when necessary.  Comes with a clear stick on cover for the face of the ipod to resist scratches or smudges.  Great product!
