Got to admit I have never worn a helmet whilst snowboarding. Then again I haven't snowboarded for over 4 years. I ALWAYS wear a helmet while kiting no matter what the wind speed is.
The last time I went snowboarding I was out on my own. It must have been a sunny day cause I remeber I was quite hot. I took an off piste route down a small valley and must have slammed somehow. The next thing I know I am sitting in the snow thinking whoa my head hurts, and why am I so cold?
How long had I been lying in the snow? No Idea
Would anyone have found me? Wasn't a well used route so again no idea
Would a helmet have prevented the 3 day headache? Almost certainly Yes
I now know that I will always wear a helmet whether on or off piste.
