Though initially i had problems with the shippment if the product viaterra came through with responsive support and work with it , i didnt recieve liners and chest protection but they sent the missing items as i bought it to their notice , recently had a very bad crash , due to drunk drivers on the road . I flew 35 meters away sliding on concrete , not only my jacket survived it with almost no damge i to had minimal injuries , which was only due to getting tossed over , no bruise , no blood , people who saw the aftermath of the accident asked if the rider had been taken to the hospital as the car was totalled but i came of with no injuries thanks to viaterra miller jacket sadly tore my rain layer but i am very happy my jacket and me and my bike got through minimal damge , almost none very happy with its fitting ventilation , drawback is its heavy but it saved my life so i am fine wearing it all its life . Great product highly recommend
