I live in Phoenix, AZ. This helmet is okay in the winter, way too hot in the summer. I bought it to replace my old Giro Hex (still available new now). The hex does not have MIPS, but it is way better ventilated. So I find myself continuing to wear my old helmet, and this sits on the shelf. Additionally, this helmet comes down much further around the head. Probably great for safety, but crummy for comfort. Not only does this increase the heat factor, but it makes it very irritating to wear sunglasses, as the helmet almost rests on my sunglasses. I would not buy this helmet again, and I wish I had just bought another Hex.
Great fitting helmet, previous reviews pointed me in the right direction! I have a fat head and this fits me great! Much better than the road bike helmet I was wearing in the woods. Great back of the head coverage, very lights feels great no quirks at all!
Historically, Giro helmets fit me well, but this one always rotates on my skull such that the brow piece encroaches on my eye, forcing constant readjustments. This is because of the shape of the lower rear part of the helmet cutting in more aggressively than my head shape allows. It just doesn't fit my head correctly.
I came from a Giro E2 which was lighter and much cooler. It's still winter in Santa Cruz, but my head is cooking every ride. Another thing I've noticed with fewer vents is that it's much harder to scratch my head. For colder climates, and different shaped heads, it's probably a great choice, but I need to get something else.
