I am looking for either a fuel belt with a single bottle or an item that i can add to my existing fuel belt (few gel holders and small phone/key pouch). I'm looking for one with about the same size volume bottle as below -

I'm struggling to find one with a single bottle system, really don't drink that much in training/events and multiple bottles aren't needed.
