Using a soft measuring tape, measure around the crown- The largest diameter around your head.
Start approx 2cm (0.78 inch) above your eyebrows, keeping the tape above your ears, and around the back of your head at the largest point.
Compare the measurements with the head circumference details (cm / inches) at the bottom of the helmet product description to determine which helmet will fit you best. This can be easier if you have somebody to assist you
Remember that the helmet size you choose should fit around the crown of your head comfortably with no pressure points. The cheek pads 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 and not slide across your face.
