 It's important to get the correct fit with any helmet, and especially one you will be wearing for many hours a day, and hopefully owning for a long time.

Measure the distance around the widest part of your head with a fabric tape measure, or piece of string.

This measurement is usually just above your eyebrows (1/4 of the way up you forehead approx), and above your ears.

Make note of this measurement in centimetres - this is your helmet size.

Use the table below to find your size as donated by the helmet manufacturers. – for example, if the measurement around your head is 58cm, you should select a medium size helmet.

Your helmet lining will compress slightly with wear, so remember when you try it on that is the 'tightest" it will ever be. You are aiming for a fit that is snug, but comfortable. You don't want the helmet to "flop" around on your head (especially when new). 

If you quickly snap you head forward and backwards the helmet should not move on your head. Nothing worse than seeing only the inside of the visor when you are just about to splat a 6ft wall!

Take time to get your head measurement correct, so you get the right helmet first time. If for any reason you don't like the fit we are always happy to swap it for a different size, brand, colour etc etc.
