When you need to purchase a new motorcycle helmet, whether it is a full-face, off-road, flip-up or any other category, it is necessary to buy it in the right size. This for safety reasons, as only the correct size is able to best protect the motorcyclist's head in the case of accident, but it is also a matter of comfort, both in terms of fit and maximizing the visibility, ventilation and aerodynamics of the product. 

To find and know your size, simply measure your head circumference using a common tape measure, placing it in the temple area, about 2 cm above the eyebrows, then wrapping the head completely trying to keep the tape always at the same height. Once you have obtained a value in centimeters, you need to compare this number with the size tables of the product you want to purchase, available on our site under each Airoh helmet, in the description of each model features of. If your measurement value is between two sizes, it is advisable to choose the smaller one, but in any case, it is always a good practice to physically try the helmet before purchasing. 

Once worn, the product should fit perfectly, adhering regularly to the whole head, you may feel a slight compression in the cheek area, near the cheek pads. The real test of fit, however, the one that can really be useful for finding the perfect size for a motorcycle helmet of any category and type, consists in moving the head in all directions, if the product moves excessively, slipping on the head and face, the size could be too big, if instead it remains firmly on the head the size should be the right one. It should also be emphasized that there are products that allow the "customization" of the fit, allowing you to replace the crown padding or cheek pads with a smaller or larger size based on the needs of the biker. Adjusting the fit, it is possible to maximize the safety and comfort of the helmet, this can happen if the size of the shell and the features of the product allow it.


How do I choose the right helmet size?

Any type of motorcycle helmet has its own features that could affect the product noisiness, a clear example is the comparison of a full-face helmet with an urban jet, for obvious reasons, the first will be the quieter of the two, it is exposed to less turbulence while driving thanks to its protection in the chin area. For motorcyclists who are more sensitive to noise, there are some small tricks that could reduce the sounds perceived during a motorcycle trip even at higher speeds. 

First of all, it is necessary to have n helmet of the correct size, a product that is too large would leave room for annoying and noisy air vortices inside the helmet. One more trick concern the use of the stop wind and nose cover (where provided) is recommended to reduce the entry of air in specific areas, in the same way, closing the air intakes (when possible) could have several benefits from this point of view, as well as traveling with the visor completely closed. In addition, incorrect installation of Bluetooth communication systems could negatively affect the silence of the helmet, leaving more room for air to infiltrate the product. The type of motorbike and the riding posture also greatly influence the noise, more exposed the biker is, greater the turbulence around the helmet and the perceived noises will be.
