I bought this product after I got ran over twice while racing and ended up with two broken ribs, a punctured lung, collapsed lung, and bruised lungs. I was wearing a EVS under protector in the crash and once I got out of the hospital I decided to go and get the highest quality and most protective protector avaliable. The A-10 was the only one that came to mind and even though the price is a little high it is worth every penny... and I mean every penny. I'm 5'9" ish and the protector is adjustable so it fits me perfectally. The quality is awesome and it feels like I am not even wearing a protector while riding in the trails or racing on the track. I know it's alot of money for a protector but it's cheaper than 4 days in the hospital.
