To achieve proper helmet fitment, begin by finding your head circumference size using the method described below.
Remember that the helmet sizing you choose should fit around the crown of your head comfortably with no pressure points.
The cheekpads should fit firmly around your face. Once your chin strap is fastened, grab the chin bar of the helmet and move it side to side.
Your cheeks should move with the helmet, which should not slide across your face. Different thickness cheekpads can be purchased to obtain the perfect fit.
Head Measurement Instructions.
Wrap flexible tape measure around your head approximately on inch above eyebrows and ears. Use this measurement (in either inches or centimeters) to find your helmet size in the chart below.
Comment: got this as a replacement for my XTS.sits higher on my head than the lower xts.. a bit heavier also due to the dropdown sun shield, but not enough to discourage its use.the sun sheild is small and is a tight fit rx lenses under.. prefer the XTS but the helmet fit and feel is good and the price is reasonable
Best Answer:This is an adult helmet so no size of this model would work. There are children's helmets, do a search for them on jafrum and you'll find a few models to choose from. For a 5 year old I'd start with an extra small, you may have try a few sizes to get the correct fit.
