If you are so inclined, the Transport Research Laboratory (TRL) have a helmet survey on the go, in their words -
"to aid understanding of whether motorcyclists purchase helmets that are the best fit. By completing this survey you will provide valuable data which will allow TRL to explore motorcycle helmet fit and potential factors that may influence the quality of this fit."
Only takes a few minutes. But you will need a tape measure. Got Rachel to measure my head and confirmed that I had a bigger head than she has. Now there's a surprise........
