Stone Island Overshirt in Plum. The overshirt is a classic piece from Stone Island, which is continuously renewed and updated throughout seasons. This season it is presented in a dark plum colour-way, still in the same cotton material for a soft and comfortable feel. The overshirt has a two way zip fastening down the front, with two stud fastening chest pockets. The collar of this garment holds studs so you can change the look of the collar to fit your preference. As a statement finish, the Stone Island compass badge is shown to the sleeve.
