AirBreaker 2.0

I was skeptical about the weight claim, but it's genuinely the lightest helmet I've ever thrown on — barely notice it's there after an hour of climbing. The ventilation keeps my head cool even when I'm pushing hard up a long incline.

The vents on this thing are unreal — even on a steep climb in July heat, I never felt my head baking. It's so light I forget I'm wearing it, which is exactly what you want when you're fighting for position at the line.
