1. Measure Your Head

  Determine the circumference of the widest part of your head by wrapping a flexible tape measure around it.
  Generally, the widest part of a person's head is the area one-inch above the eyes and ears. However, we do
  recommend measuring a few spots above and below that spot, then refer to the table below using the greatest
  measurement.

  Hat sizes are included in the chart for reference only, and should not be used exclusively when deciding on
  a helmet size. To find the best fit we recommend that you also try-on a helmet one size smaller and larger
  then what the chart indicates. No helmet can provide protection if it’s too uncomfortable to wear.

  2. Wear The Helmet
  Helmets must fit snuggly, but not painfully tight. While holding the chinstraps outside of the helmet, pull
  it down over your head taking care that the chinstraps do not go up inside the helmet. A properly-fitted
  helmet will feel snug with fairly even pressure around the sides and top of your head. On most modern helmets
  the inside comfort lining is designed to be a little extra snug at first, but after several hours of riding
  it quickly forms to match the shape of your head. If you are not familiar with how a helmet should fit and
  feel, be sure to ask for assistance from the retail store or a more experienced rider. As a rule, the helmet
  should not be able to move around on your head without pulling on your skin. A loose fitting helmet is not
  only dangerous, but may also be noisy and tiring to wear. Most people make the mistake of buying a helmet
  that's too large.

Safety Reminder:

  No helmet can protect the wearer against all possible or foreseeable impacts. A helmet can only protect
  the portion of the head that is covered by the helmet. For maximum protection, the helmet must be well-
  fitted with the chinstrap securely fastened. Failure to follow these instructions, the instructions
  printed on the helmet and in the owner’s manual may result in the possibility of the helmet coming off
  during an accident - possibly resulting in a severe head injury or even death.
