Our Fit Process

The first step in the fit process is to measure your head.  The best way to do this is to find a soft, fabric tape measure which you will use to measure the circumference of your head. You want to measure over four spots: the center of your forehead, above each ear and to the base of your skull.  It should feel similar to where a ballcap would fit around your head. Refer to the centimeters on the tape measure and compare it to the chart below.  Another key point to note is that different brands of helmets have different shapes.  If your head is more of an "oval" shape, you will most likely fit better into a Sweet, Giro or Pret helmet.  If your head is more "round" then Smith, Anon, Poc and Oakley might be a better choice.  

The best way to know if the helmet will fit is to try it on, which is why we offer free returns!
