This jacket has barely been used. It’s been on my bike in a waterproof bag for a short time but only worn once or twice. It’s in very good shape, nothing to report in terms of issues. There is an outer layer, AC3 vented on the arms and chest - breathable. An inner layer, which is insulating. And it comes with four pads, back and elbows. It is a fitted style, Not baggy. Not a lot of room for extra layers beyond the included inner insulated layer.
