To know what size helmet you should wear, you need to start by measuring the circumference of your head. Measure just above your eyebrows. The measurement indicates what size helmet you should have, so the helmet size is the same as the circumference measurement.
EQ3 Lynx is available in three sizes: Small, Medium and Large. The helmet has a screw function at the back which allows you to adjust the size more precisely. Lynx also has replaceable Coolmax® inner liners which are attached to the helmet with Velcro. With the different inner liners, the fit can be adjusted for an individual fit to your head. The liners are more padded on the sides which makes the size and shape of the helmet very adaptable.
In the table below you can see which size fits your measurements, as well as the thickness of the inner lining in each size. When you buy a Lynx riding helmet, the Lynx Original helmet lining is included as standard.

A perfectly fitting riding helmet should sit comfortably on your head without pressing anywhere. The helmet should stay firmly in place when you move and the chin strap should sit securely under your chin.
If the helmet is pressing on the side of your head and forehead, you need a helmet that is more oval in shape. If you feel that the helmet is not quite coming down on your head and that it is not sitting firmly, you probably need a helmet with a rounder shape.
There is another way to check if the helmet is properly fitted using the traditional “shake test”. This is simply done by shaking your head up and down with the chin strap unfastened. If the helmet stays in place then the helmet is well fitted. If the helmet falls off then the helmet is probably too big.
We offer a wide selection of inner liners in different thicknesses that allow the size and shape of the helmet to be adapted to the individual. All inner liners are easy to replace as they are attached with Velcro inside the helmet.
The chin strap should be taut and positioned properly under the chin. It should not slide forward on the chin, but should be tight enough to remain stationary. The strap is in good condition when you can fit one to two fingers between the chin and the chin strap. On all our helmets there is a small triangle at the end of the chin strap that allows you to adjust the chin strap so that it is positioned properly under the chin.
If you want to ride with your hair inside the helmet, it is important to keep this in mind when trying out your riding helmet. Sometimes you may need to go up a size to accommodate your hair, and if you ever choose not to wear your hair inside, the helmet may be too big. We recommend choosing an adjustable helmet so you can adjust it to how you want your hair.
