A friend of mine had a very bad accident about two months ago. Air lifted to hospital. Shattered left knee,both ankles broken and pins,screws.You name it but he was wearing a Nolan flip helmet and had nothing happen to his head. Helmet took it all. Just came home three days ago ,will never ride again after over 50 years of riding .I was with him but I still can't wear a full face. Mikey
