Bag for Running ?

[polygraph]

Not exactly sure what I am looking for or if I have seen this before for this specific purpose. I am looking for a bag (kind of like a fanny pack) for running that will sit around my waist. Not looking for the small MP3 player cases but something to hold my MP3 player and a couple other (light) things. Right now I am using one of those travel money packs (pictured below) because it’s flat and light but I find it always slips and doesn’t sit flat.
