At £120 for this helmet, it's nice to see that Giro isn't trying to take us for a ride with the Air Attack.
Without the use of a wind tunnel, it's hard to argue with the aerodynamics of this helmet.
One thing that is certain, though, is that it's not the quietest lid I've used.
It's now had three evening races in mixed conditions, and it's one for the classics.
Obviously, everyone feels heat in a different way, and I'm usually cold, yet found I didn't want to race in it once the arm-warmers came off - it felt just too warm.
