First of all, ordering from biketiresdirect.com is super easy and I love the points system. The helmet arrived before I expected, which was in the middle of winter so didnt really get to wear it right away on my bike cause its too cold in this state. The helmet fits great, looks cool and Im assuming will protect my brain and head from injury. Hopefully, thatll never happen. So, I guess I cant comment on its efficacy. Anyway, its comfortable, light weight and fits like a glove...for my head.
