If you are still unsure, there is the option for visiting our facility in West Sussex and having your head measured by a qualified Alpha Helmet specialist, and also to try on the suggested size.




Head Measuring Instructions

1. For measurement [B] and [C] a head measuring calliper will be required. These are available from Headset Services Limited on request.

2. For measurements [B] and [C] ensure the callipers are pressed against the skull. Slide the callipers back and forth to locate the maximum measurement.

Both comfort and retention are key to selecting the correct size of helmet. Should a head size fit into two options, the smaller size of helmet should be selected wherever possible. If any of the measurements enter the range for the next largest helmet then that is the size that should be selected.
