Giro Ionos Cycling Helmet 2014

The most ventilated and technologically advanced Giro helmet. Features the new RocLoc5 retention system - a claimed 40% lighter than its predecessor but, according to Giro, is more durable with examples during testing withstanding more than 6500 test cycles or three years' riding with an average of three round trips per day. A proprietary in-mold composite sub-frame (I.C.S.) provides the strength to support 21 of the largest vents ever carved into a helmet making Ionos the coolest, best-ventilated helmet available. Perfect for keeping Grand Tour champions like Lance Armstrong and Alberto Contador cool on the hottest days.

• Fantastic styling and exposed I.C.R. carbon fibre detailing.
• A visible weave of composite called In-Mould Composite subframe, runs throughout the helmet liner and around the vents.

This is a European standard and although the helmet is perfectly safe to use, specific countries may have their own certification which is legally required if you intend to wear the helmet recreationally or in a competitive racing environment. If you are unsure, please check your specific country requirements and check with the manufacturer to see if the helmet has received any additional certification.
