The Giro Phase Bike Helmet features tons of venting to keep your melon cool during those mid-summer rides that you regret letting yourself get talked into. It's kind of nice to drop those spandex-clad über-climber bike-shop buddies that talked you into coming, though. It looks like they could have saved the $300 that they spent on their helmets for a helmet like yours that actually vents.

• Acu-Dial fit system for a custom fit
  
• 27 oversized vents keep the air flowing
  
• Snap-fit 2 visor keeps sun and debris from getting into your eyes
