GIRO AEON HELMET most ventilated 2012

Product Description

THE GIRO AEON™ - THE LEADING COMBINATION OF LIGHT WEIGHT, COMFORT AND COOLING PERFORMANCE. Imagine a helmet that gives you an advantage every time the road climbs or the heat turns up. Until now, you couldn’t get the benefits of lighter weight and better ventilation in a single helmet. But the new Aeon weighs only 222g in a CPSC approved size Medium. Yet it also provides cooling power equivalent to the most ventilated helmet ever made, the Ionos™. Plus it offers the luxurious feel of Roc Loc® 5, and an innovative thermoformed Roll Cage reinforcement. If you’re looking for the best balance of weight, ventilation and comfort, this is the new standard.

Fit System:
Roc Loc® 5 

24 Wind Tunnel™ vents, internal channeling

  With an ingenious structural design, incredible ventilation and a nearly weightless feel, the Aeon racing helmet is certain to be the envy of the pro-peloton. Structural support and long ventilation channels create more "air space" around your head for a cooler experience. Features Giro's new ultra-light, ultra-strong, Thermoformed SL Roll Cage -- a whopping 49% lighter than the sub frame used in the Ionos helmet. Add on the Roc Loc 5 fit system, Tri-Locs, Slimline webbing, and logo-printed pads for even further weight savings and an unbeatable fit.

  • In-Mold construction reinforces the area around the vents and ribs, creating a one-piece exoskeleton, which allows the helmet to be lighter, more durable and better ventilated than traditional designs
  • Thermoformed SL Roll Cage support system is 49% lighter than the one used in the Ionos helmet, yet is still incredibly strong
  • Lightweight EPS foam is 15% less dense when compared with the Ionos helmet
  • 24 sweeping Wind Tunnel vents with internal channels thrust 15% more cool, fresh air over and around your head while forcing heat and stale air out
  • Impact absorbing, antimicrobial X-Static padding with printed logos offers unprecedented comfort and manages moisture
  • Quite possibly the best-fitting retention system you've ever experienced, the Roc Loc 5 easily adjusts both fit tension and vertical position with a single hand, plus its 40% lighter than its popular predecessor, Roc Loc 4
  • MicroTech Tri-Locs, ultra-light Slimline webbing and metal badging reduce overall helmet weight by 36%
