Product DescriptionSize ChartProduct Review

Icon Alliance Rat Helmet is brand new to the Icon line of helmets. The Alliance line of helmets has been evolved & refined. Icon has never been satisfied with the status quo - which is why they created the new Icon AllianceTM helmet. Based on the proven Alliance SSR, this nexgen helmet is fitted with a multitude of key refinements. The first revision is the new EPS liner. They’ve listened to the customers’ requests and reshaped the EPS liner into a more oval geometry. Combine this geometry with a removable Hydra-Dry™ moisture wicking comfort liner and the result is a nearly perfect rider focused enclosure. To further increase rider comfort they’ve revised the entire venting system. Much like a finely tuned motor, they’ve reshaped and enlarged the intake and exhaust ports for increased airflow. Additional ventilation ports have also been added to the lateral aspect of the helmet to further increase ventilation. The shield itself has been upgraded to Icon’s distortion free Pro-Shield™. Continuing with our commitment to excellence, the Alliance is constructed with premier manufacturing processes and stringent quality assurance procedures.

How to measure your head for the right helmet size
Get a measuring tape marked in centimeters. This is important, since centimeters are a smaller unit and will produce a more accurate measuring result. Have a pencil and paper ready to record your measuring.

Take the measurement around the circumference of your head at the widest point above the eyebrow bone, over the bump at the rear of your head and just above the top of your ears. Use a mirror as an aid, if unsure whether you are measuring correctly.

Check your measurement with the helmet size chart above and select the nearest size. If you can't find a helmet size that exactly fits your head measurement choose a helment size just smaller to your head measurement.

Important:Your helmet fit is not only critical to the comfort and enjoyment of your helmet, it also plays a critical role in the performance of your helmet in the event of a collision. Never purchase or wear a helmet without ensuring a snug fit.
