The back protector is considerably thicker and the first impression for integrated thinner supplied as standard Büse jacket protector rigid and "bulky". Nevertheless, you get him relatively easily in the corresponding protector pocket by gently bend. The first support is then attempt .... strange, but after a short time he is due to the adaptation of the material pleasant to the back and is not surprisingly noticeable. For the 5 star it is not enough for me, because I would like to see a better back ventilation.
