Today I received it, I won't give it four stars because I haven't even tried to see how many clothes it can fit inside. It is deep and minimal in material, of course it depends on what you put in and how folded it is to fit. I think it's perfect for two or three days, just as I saw it. The only thing that bothered me was that the shoulder strap inside matches exactly the color of the bag, but the brand is Beishit and not Emerson. Similar companies exist in windbreakers and clothes, but regardless, I didn't expect that. Otherwise, it fits perfectly. I will come back when I travel with it or when I try how many things it can fit inside
