This helmet has got it all for pretty cheap. I've worn this thing on my daily 13 mile ride through rugged terrain on Acadia NP trails in Maine. With rocks the size of softballs and speedy downhill slopes, you're gonna fall. This helmet products my massive dome.
I also have a huge head (7 5/8 + thick hair) and usually have trouble finding helmets that fit. The snap adjustment in the back is quick and secure. Cheers 661, I'll be buying more gear from y'all.
