Smith helmets are bad ass and the new Maze is the lightest, most low profile, fully certified helmet in the world. But dont take my word for it, check out this post from Corey Felton's blog
"Few things came out of this event. One I will never ski without a helmet. Smith has a new helmet next year called the Maze and this helmet saved my life. There are 3 big dents in it but that helmet saved me from a concussion or possibly worse."
I also know that Mike Riddle smacked his head really hard in the pipe and was stoked on how the helmet kept him from getting knocked out or getting a concussion.
So yeah, Smith helmets will save your ass in the park or the bc
