Giro Eclipse Spherical Bicycle Helmets

Every other helmet ive ever owned has been sized large but i take a medium in this one and it fits so very well! I appreciate the aero benefits and it doesnt get too hot which other aero helmets can do. Customizability of fit via the rear dial is a breeze. Sweat channeling/routing is on par with other helmets. Only take off 1 star because at this price, closure should be magnetic.
