It looks good except when I put it on my head and it becomes this enormous cradle around my cranium. Acutally it looks ridiculous.
Giro claims it's their most advanced road helmet and it has what it calls 'wind tunnel' ventilation. But I don't agree, it's no cooler than my five year old Limar, and it has the same number of vents.
On the positive side, the new improved Rock-loc 5 works well and is easy to use. Although the dial is teeny, compared to the rest of the helmet.
I suspect the autographed version by the seven-time TdF champ has something to do with the $300 price tag, but at half the price it's still a questionable purchase.
