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 AGV K3 is one of the classical top selling helmets by AGV. Its design derives from the top of the range GP-Tech helmets, bringing most of the latest advanced features on this reasonably priced product. The K3 uses AGV's well proven HIR-TH (high resistant thermoplastic) resin shell construction, this shell is very strong and has excellent shock absorbing properties, however the manufacturing process is much quicker and simpler than an equivalent fibreglass shell. This ultimately is reflected in the price of the helmet enabling riders on a budget to have an exceptionally safe and well made product at the fraction of the price you would expect to pay for a premium branded helmet. With a Dynamic ventilation system, aerodynamic front intakes and rear extractor with fully removable, washable Dri-Lex lining with Sanitized antibacterial hygienic treatment.
