Familiarity: I've put it through the wringer
I really like the way this fits my head, its very comfortable. It also seems to go low on the back of my head and protect my brains.
It is hot though, the ventilation is not that great compared to most XC helmets, but it does protect better. So I would take extra heat for extra protection.
