Giro's Aeon is the pinnacle of lightness and comfort and a great choice for your road riding. This trick lid dropped 28% off the weight of its predecessor, while actually adding features. For durability it boasts Giro's In-mold polycarbonate shell with a reinforced thermoformed Giro SL Roll Cage, and for comfort there are 24 vents with Giro's Wind Tunnel technology to draw the air through. Complementing the ventilation is Giro's Roc Loc 5 retention system for a custom fit and feel, plus Giro's antimicrobial X-Static padding for ride all-day comfort.

After a recent cycling mishap left me with two fractured ribs, pneumothorax, and three days in the hospital, I count myself extremely fortunate by not incurring a serious head injury. While my Giro Aeon suffered three breaks in the shell, it remained intact and absorbed the impact in magnificent fashion. I am heading to [...] today to purchase a replacement.
