No. It is important that a helmet fits well if it is to provide its best protection – studies estimate that between 10 and 14% of fatal injuries occur when the helmet comes off in an accident. This is why the SHARP website includes a video that offers advice on helmet selection. Comfort is also important and should be considered when making a purchase. An uncomfortable helmet can distract you when riding and a poor fitting helmet may offer reduced protection in the event of an accident. The safety rating is a third criterion that can help make this important purchasing decision. Other factors may influence the purchaser but SHARP offers no opinion on what are largely subjective assessments.
