Giro Chapter 2
Here's what other sites are saying:
Giro cut so many ventilation channels into the Chapter 2 Helmet, you might swear you feel the wind ruffling your hair. Well, that may be an exaggeration, but this could possibly be one of the most well-ventilated snow helmets around. Whether you tend to 'run hot' in general, or you habitually seek out heart-pumping, thigh-burning excitement, the Chapter 2 will protect your noggin from run-ins with both animate and inanimate objects without causing you to blow a gasket.
