It has protected my head on several occasions so far, it's a little scratched up but works great. It's comfortable, the fit system really lets you customize your fit, it has plenty of air flow and it's light.
The only issue I have with it is that if your scalp burns easily (mine does, through my hair), you'll want to wear scalp sunscreen or get one of those head sock things. I would assume this would be an issue with any helmet with good air flow though.
