I personally dont feel sae in any mtb helmet besides the Troy Lee Designs D2. Its reminiscent of a solid mx helmet. I know theres a few really weak mtb helmet thats i wouldent think twice about using up in whistler. My D2 has saved from quite a few scars. If they didint have this one..I would use a motov helmet definitley because all the other bike helmets just dont offer enough pretection in my book.
