iPod Nano Silicone Case Package for 4th Generation Skin Cover + Screen Protector + Car / Home Charger / USB and Armband, Nike + Compatible
I bought this package two years ago, and all items are still going strong. I'm an avid gym-goer, and the arm band gets used daily. The only issue is that if I'm running, I'll have to wear the ipod upside-down, because it can slip out of the case. But it's not a big deal to me. Great bang for my buck.
