The Plus One is an easy way to add capacity to any of Fuel Belt's belt designs; it's a 7oz. bottle in a plastic molded holster with a belt loop for attachment. This is an excellent way to add more volume when you need it and works particularly well with Fuel Belt's Revenge collection and all of their 2-bottle belts.
