Once you have found a motorcycle helmet that fits, try it on.
It should not move when you shake your head and you should not be able to remove it without undoing the chinstrap. It is also important that you feel comfortable in it.
Be aware of the slightest discomfort
Keep the motorcycle helmet on long enough at the fitting to detect any discomfort.
You should not feel any unpleasant pressure on your temples, forehead or neck. If discomfort is felt in these areas at the first fitting, it may get worse over time. You should then try another motorcycle helmet. There is only one area where you should feel tight and that is in the cheeks. At first this may seem uncomfortable, but the foams will settle over time, which will increase comfort without losing support.
Note that even if the size fits, some models may feel uncomfortable because of an incompatibility between their shape and your morphology. There is nothing you can do in this case, except to try others.
Check the accessories
Manipulate the sun visor, the vents and other accessories to ensure that everything is easily adjustable.
Tighten the chinstrap to check that it does not bother you (you should be able to put two fingers between the strap and your chin).
Put on your glasses
If you wear glasses, make sure you can wear them with the helmet without being uncomfortable. Some motorcycle helmets have grooves that allow the temples of the glasses to be inserted.
Check the weight of the helmet
The weight of a motorcycle helmet can vary according to the materials used: there are polycarbonate helmets which generally offer a good quality/price ratio, fibre helmets which are more resistant and multi-fibre helmets which are both resistant and light.
We recommend that you keep an eye on the weight criterion as it is important for your comfort. A motorcycle helmet that is too heavy may be uncomfortable on long journeys as it puts pressure on the neck. On the other hand, a helmet that is too light may be unbalanced, with the weight either too far forward or too far back.
Ideally, an adult helmet should weigh between 1.2 kg and 1.4 kg.
