arm band case for Razr maxx?

[wabi515]

Can anyone recommend an armband case for the Razr Maxx? I'd like one that fits the phone well and is pretty much waterproof, in case i get caught in the rain. I have seen them on ebay and amazon, but they look like they are trying to make a one size fits all. I run a lot, so I want one that fits the razr maxx well.

Any suggestions?
Thanks!
