Details: You wanted a lighter helmet, a cooler helmet, a better helmet—so we 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. We 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.
