How To Buy A Helmet
To determine your helmet size you need to measure your head.
•A downloadable tape measure is available at boeriusa.com. Wrap it around your head above your eyebrows. The usual range is between 51--63 centimeters.
•Once you determine your size, you should try on a bunch of different models in the correct size.
•Find one that fits snug with the pads making contact all around your head--no side-to-side or front-to-back movement.
•Narrow it down based on which one you like enough to actually wear all the time.
•And finally try on your goggles with the helmet to make sure everything works together.
