Armband?

[Simon_y7]

Anybody would venture a suggestion for a good quality sports armband for Rezound that would both keep the phone in securely and would't keep slipping down the arm? I saw one made by Griffin for iPhone at the gym today. Looked just what the doctor ordered, but Griffin doesn't appear to make armbands for Androids. I tried one from Radio Shack, but it didn't stay in place, so I returned it.
