Helmet Fitting Guide
1. MEASURE YOUR HEAD
Never just guess your helmet size. Before trying on or ordering any helmet you need to make sure you know your head measurement. Measure around your head just above the ears and take a measurement at the forehead. This measurement is the best starting point and will correspond with most helmet manufactures helmet size. Making sure you get the correct fit is important; don't be tempted to go for another size if your choice of helmet is out of stock.
2. TRY IT ON
Place the helmet firmly on your head, securing the chin strap so you can fit two fingers between the helmet and your jaw. If the helmet has a quick release type buckle then adjust the strap a necessary. Once on your head, you should be able to feel the helmet against the whole of your head without feeling and pressure points or the helmet leaving red marks. Keep it on your head for a few minutes to make sure it's comfortable after a bit of time.
3. CHECK FITMENT
Secure the chin strap and try rotating the helmet from side-to-side. If you're wearing a full-face helmet your cheeks should follow the helmet's movement, while remaining in contact with the cheek pads firmly and comfortably. If the helmet moves or slips on your head it is probably the incorrect size. The next test is try tilting the helmet forwards and backwards, also if the helmet moves or slips it's probably the incorrect size.
4. IS IT SECURE
To test the helmet you are buying will stay firmly on your head in a crash, make sure the chinstrap is done up and tilt your head forward. Get someone to try and roll the helmet off your head by carefully pushing up from the rear of the helmet at its base. If the helmet can roll off with this test, then it will not be safe in a crash.
