How to Measure
To find the right helmet size, measure all the way round your head at the widest point. Keep the tape measure above your ears and make sure that the tape measure is not too tight, nor too loose. Take your measurement in centimeters (cm), not inches.
Checking for Best Fit
When a new helmet is first worn, it should actually be slightly tight, with the interior coming into contact with most of the head, but not so restrictive that it causes any pain. There should be no "hot spots" - places where the helmet's interior puts pressure on specific points of the skull or face - but it should not move around freely. With time, a helmet will adjust to match the shape of the rider's head as it is worn and goes through "break-in" and loosens up a little. However, it should never become loose enough to easily turn from side to side.
Put the helmet on - it should be a little tight as it goes on over the head
The helmet should sit on the head evenly with the eye port's upper edge sitting just above the eyebrows and have good peripheral vision available to see side-to-side
Try putting a finger between the helmet interior and the head. If it easily fits, a smaller size should be tried next. Note that some helmet models allow for the cheek pads to be changed out for better fitment, so consider this too when checking for proper sizing
The Arai Tour-X 4 is made with SFC (Super Fibre Construction) and a triple density inner shell, providing great protection for the rider. It has a high level of ventilation - two TDF3 front ducts, side exhaust vents, patented visor brow vents and more - that make it a great helmet to use even in the hottest of environments. Its FCS (Facial Contour System) with removable 5mm foam layer on the cheek pads allows you to achieve the perfect fit when using the helmet for the most enjoyable ride. It is fitted with the Arai standard double 'D' ring fastening system, ensuring correct strap tension at all times. The styling of the helmet is unique and adjustable - you can wear it with or without the peak, with or without the visor or a combination of the two. The interior is Dry Cool and fully removable and washable, keeping the helmet in great shape after repeated usage.
