Giro Aeon Helmet

Redesigned with weight and ventilation in mind, the Aeon from Giro is poised to deliver high-end performance to even the most demanding cyclists.

For this version of the Aeon, Giro optimized every component of the helmet, even the shape of the helmet itself, resulting in a 28 percent weight reduction compared to the previous model. Giro's in-mold construction process fuses the helmet's outer shell with its impact-absorbing EPS liner during the molding process, making the liner literally a part of the helmet. This process reinforces areas around vents and ribs, creating a one-piece exoskeleton that allows the helmet to be lighter, more durable, and better ventilated than traditional designs. The proprietary Wind Tunnel ventilation system, combines active vents with internal exhaust channels that thrust cool, fresh air over and around the riders head-while forcing heat and stale air out. The significant increase in air ventilation gives you an advantage on tough climbs and when the weather gets hot. Giro spent two years fine tuning the Roc Loc fit system to bring you Roc Loc 5, a groundbreaking fit system with an unmatched level of comfort, stability, adjustability, and weight savings. With Roc Loc 5, you can easily dial-in both fit tension and adjust vertical position with a single hand. Twist the ratcheting, micro-adjusting dial for a tighter fit on rough terrain, and back it off a bit and relax across the flats or a warm climb. A three-position bracket allows for 15 millimeters of up/down movement for easy fine-tuning of vertical positions. Even with these impressive features, Roc Loc 5 is 40 percent lighter than its popular predecessor, Roc Loc 4.
