I bought this helmet about 2 years ago, the helmet spent most of its time sitting on the top shelf of my safe, and was only occasionally brought out for training purposes.
A few weeks ago a friend invited me out on a bike ride down a very steep several mile mountain road, with the goal just being to ride as fast as we can. I am not much of a bike guy, so the night before I ended up grabbing the helmet to take on the ride. I looked pretty funny, but it was a good thing I took it.
3/4 of the way down the mountain I hit a rock and was flung over the handlebars at about 25mph, and hit the pavement head first. The helmet absorbed all impact, and I walked away from the wreck without so much as a headache. Hand bleeding and knee pads were shattered, but the helmet ate the first impact with no more than some scratches.
5 stars, protects head as advertised.
