There are different rusty colored flask sleeves to choose from. There is one that has a belt clip and its size is for a larger flask like a 12oz. There is a smaller version of this sleeve for a regular sized flask (9oz) too. This smaller version can either come with or without a buckle clip. The last option for this color is a very simple sleeve that has neither a buckle clip or piece that goes around the mouth of the flask. It is much more simple and without the extra accessories. It fits a regular flask. A small note is that the leather may vary in color tones.
