Unique properties are, the fusion of the sweater backpack. The backpack is light weight extremely thin, but expands for larger items, it is made out of an amazing material has large side pockets, a huge rear pocket for your jacket or hoodie to slide through(new tech) so much more to mention. The hoodie has integrated light weight special webular gloves designed into it by a special device, the vess is a one of the kind item as well. Need more photo space so I can show images of how meticulous the work really is.
