Giro Ionos Road Cycling Helmet

Giro Ionos road cycling helmetI chose Giro because of their history and reputation of quality and reliability.

I chose the Ionos because it was lightweight, comfortable, fit well, had good ventilation, and it looked good.  It also was the most comfortable helmet I tried while wearing sunglasses.
