Tuneband for iPod nano 4th Generation, Armband Compatible with Nike+iPod System
This is an item who's sole purpose is to reliably hold your iPod as you do your thing. When purchasing items like this, you want to forget that it is there. By that I mean that you don't want it to fall off as you exercise or the velcro to wear out. I've used it consistently for over two years several days a week and not once had I had a problem. Enjoy!
