Giro Aeon Cycling Helmet (Matte Black/White, Medium);

Maximum Ventilation, Minimal Weight and Zero Compromises. The Aeon marks a new era in helmet design. Stating with a full roster of our best features, we optimized the design of every component in the helmet and even the shape of the helmet itself to reduce weight by almost 28% overall. Of course, we also sculpted massive vents with interior channeling for best-in-class cooling power and integrated the adjustability and comfort of Roc Loc 5, too. When you want a lighter helmet, a cooler helmet, a better helmet - this is the one.
