I have been skiing many times is multiple resorts. I am an intermediate skier. I prefer the fun greens/ blues. I can ski black diamonds, but honestly I prefer the ease of skiing rather than the competitiveness. I was skiing an easy run. The run was narrower surrounded with beautiful trees and cabins. I noticed a skied off area where there was a ton of noticeable ice. I attempted to move to the right to avoid most of the icy snow. I did hit a patch, which increased my speed. It was Ll fine but right after the ice patch was a mogul, followed by another larger mogul. After having the speed from the ice hitting that first unexpected mogul sent me in a non-controlled tumble. After hitting the second mogul, I was airborne. My head broke my fall. I remember my head hitting and bouncing back. My husband was right behind me, so I loved right away. I was okay and able to ski home. I made skied away without a concussion, or even worse. I did get whiplash, but no lasting effects. I am a walking advertisement for this life saving helmet. I literally own my life to Smith ski helmets. I am BEYOND grateful for your technology, and safety features. I cannot thank you enough. If you're reading this thinking of purchasing a helmet. Do not think twice. It may safe your life too.
