Giro: GET MORE, AND LESS If you want a cool and comfortable helmet, and the lightest helmet in our road line – then you want the Aeon.We relentlessly optimized every one of our best features including the shape of the helmet itself, to reduce weight by 28 percent compared with the Aeon's predecessor. We also sculpted massive vents with interior channeling for impressive cooling power, and integrated the full adjustability and comfort of a Roc Loc 5 fit system for a secure, luxurious fit.
