    Great protectection

    Posted by Collette on 15th Jul 2017

    I purchased this helmet less than three months ago and I am very happy with it. It is very comfy and keeps me cool in the summer heat. But the best part about it is that it protected me in a recent fall when I was bucked off. I hit hard but my head was fine. No concussion, no headache but I can't say the same thing for my shoulder.
