I will swear but the Valhalla 360 evice. My son went over bad this weekend and the SKUSA Summer Nats. Pretty nasty. How ever the device did its job and then some. It kept his head in place and protected his neck during the flip and the skid on his head across the pavement. His body was bent back against the exhaust and the extra protection saved his neck even though part of it melted on the exhaust. I expecialy like the high rise part in the back of the brace that gives extra protection from the head going back. He has no loss of movement and will by the same one again after what witnessed.
