MAXIMUM VENTILATION, MINIMAL WEIGHT, ZERO COMPROMISEYou wanted a lighter helmet, a cooler helmet, a better helmet—so Giro created one. Starting with a full roster of our best features, we optimized every component in the Aeon™ including the shape of the helmet itself, reducing weight by 28 percent compared with its predecessor. Giro also sculpted massive vents with interior channeling for best-in-class cooling power and integrated the adjustability and comfort of Roc Loc® 5, for a luxurious feel with all the performance you need.WEIGHT190g (CE Medium)FEATURESThermoformed SL Roll Cage reinforcement, X-static padding, Roc Loc 5 fit system, Slimline webbingCONSTRUCTIONEPS liner, Thermoformed SL Roll Cage reinforcement, Polycarbonate shellFIT SYSTEMRoc Loc® 5VENTILATIONThe Aeon road bike helmet is designed with 24 Wind Tunnel™ vents, internal channelingSIZINGS: 51-55cmM: 55-59cmL: 59-63cmModel year: 2018
