The helmet may save you
...as it saved me.
15 minutes of being stone cold knocked out, a cracked wrist, and multiple myoskeletal injurys on my back, chest and waist later im typing this to let you know that the helmet was proven to be the best $40 dollars i have invested, on a hideously looking and unstylish piece of gear which held my scull in one piece. Hats look so much cooler but thats just about it.
Oh and also, if it happens to come across a jackass laying in front of you as you go down a very narrow slope with trees all around you, pass through him. Dont try avoiding him...
