Um... you have to remember that these bags come in different sizes?
From what i see you're not even sure if that picture is of your bag or not...
That looks like a 6 racquet bag. Maybe you've got the 3 racquet one but havn't noticed?
Just a suggestion.
i've seen someone use this bag before, and the only thing i can say about it is that it's just a normal bag stamped with yonex in every possible spot there is. technical specs i'm not too sure about apart from a convenient shoe compartment.
