Special purchase of this 2016 Aeon helmet in a discontinued colorway has led to a large price reduction. Quantities are limited on this top offering and best seller from Giro. These are available in the popular Matte Black/White color combo only.

On a hot summer's day in the mountains, or powering through humid conditions so intense you can almost see the air, there is nothing like a very lightweight, exceptionally well ventilated road helmet. It is clear now that virtually everyone agrees safety is paramount, but every helmet Giro offers passes stringent CPSC and CEN safety standards for impact protection. The Giro Aeon holds true to safety principles, yet unlike many other helmet designs, puts rider comfort, and airflow over aerodynamics. While the best aero road helmets work great, when you really want to keep cool under high output in challenging heat conditions, the Aeon is the standard bearer. At just 222 grams in a Medium size, the Aeon feels incredibly light on your head, and that experience is accentuate by it's impressive ventilation and air circulation within the shell. When comfort is more important that a handful of watts saved, grab your Aeon and hit the road.

There are multiple impact protection standards a helmet must meet or exceed for certification. Those various tests drive the limitations of open helmet shell designs. As such, Aeon uses a combination of shell design, technology, and vast experience with helmet development to offer their proprietary Thermoformed SL roll cage. This one-piece internal reinforcement structure provides excellent impact resistance in a 50 percent lighter structure than the multi-piece fiber composite structure of the previous Giro designs. The roll cage is formed from the same polycarbonate material as the Aeon's outer shell to provide double-protection with the In-Mold construction process. The compressive, dense foam EPS (Extruded PolyStyrene) liner is the component that diffuses energy at impact, sparing the skull from direct force. The roll cage then helps hold the helmet together and not blow apart, protecting you in case of multiple impacts in the same incident. While MiPS layer have brought a new level of protection, overall helmet safety still relies on this evolved method of construction. Achieving the light weight of the Aeon, while still exceeding CPSC and CEN standards represents both Giro's mastery of the technologies available, but also a commitment to rider safety and comfort....
