I would highly recommend this case if you are a runner and are using the Nike+ iPod system. I have had this case for almost a year and I still love it. I use it several times a week for running, as well as, during my training for a half marathon. I live in very hot climate and I don't even notice that I have it on my arm. The dual straps for wrist or upper arm placement make it even better. In the winter months, the wrist position works well wtih a long sleeve top. This case provides a tight fit for the iPod and the Nike+ receiver, while the clear window provides easy access for selections on the iPod. I will buy another as the neoprene is beginning to split where it has to fit over the receiver but it definitely was worth the price, considering how much I have used it.
