Your helmet size relates to your head circumference when measured just above the ears. Be sure to keep the tape measure level to get an accurate measurement.
Helmets are typically supplied in different size ranges. These ranges will be displayed under the 'size guide' tab on the product page. For a list of all our helmets please click here http://www.wiggle.co.uk/helmets/ .
