Fit tip Where two adjacent sizes share a boundary figure, choose the smaller size on an open helmet with a dial adjuster and the larger size on a full-face.
How to measure
Wrap a soft tape measure around your head from the middle of your forehead, keeping it level about 1.5 cm above your ears, which is the widest part of the head, and read off the circumference in cm. Kali sizes each model differently, so find the table for the model you are buying and pick the row your measurement falls into. Where two adjacent sizes share a boundary figure, choose the smaller size on an open helmet with a dial adjuster and the larger size on a full-face.
