How to ensure the proper fit:

There is one simple and best way to make sure your helmet fits properly and that is to measure your head. To do this properly, take a soft tape measure horizontally around your head at a height of about one inch (2.5cm) above your eyebrows keeping the tape measure above your ears. 

Next, take this measurement and compare it to our sizing chart. Note different helmets have different fits just because you were a large in one helmet brand doesn’t mean you are a large in every helmet. Since the helmet may not always exactly meet your head size, and your head measurement may fall between two sizes, first try on the smaller size, it is better to have a more snug fit than a loose fit.  Most of our full face helmets offer adjustable cheek pads and this will usually allow for a more custom fit if necessary.
