Does anyone know where I can get one of these?

Hey, I am looking to get one of these, the thing is, the search terms I am using don't help and a google image search just pops up bags. It is the actual pouch I am after, so if anyone know what they are actually called or where I can get one, I would be so grateful. Thanks guys!
