I have a couple I regularly use. I have a red, white, and blue Giro Atmos that is great! I also have a Giro Pneumo that is dark blue and black and matches the bike nearly perfect (go figure). The Atmos is a slightly nicer helmet, but being an OCP I usually rock the Pneumo. If and adjustment is excellent on both helmets. My wife likes the Giro Monza, also a nice helmet.
