To be able to offer effective protection whilst remaining comfortable, a helmet must be perfectly adapted to its user. Choosing the right size is essential.
1) Measure your head circumference using a tape measure. Position it about 2 cm above the eyebrows and take a measurement around the widest part of your head placing the tape across the temples and around the back of the skull and back to the forehead.
Once the measurement is recorded, compare it with the size chart. Try the size of the helmet closest to the measurement you obtained but if you fall between sizes always start your test with a smaller size of the two.


You should feel an all over even pressure across your head with the helmet unable to twist or move around, a firm but comfortable fit without pain.
If you feel a hard contact point or major discomfort, try the larger size.
2) Size tests must be performed with the chinstrap fastened.
Make sure you have a good vertical and horizontal visibility. Make sure your head can perform all its normal movements without any problem.
With the chin strap secured, make sure that the helmet can not be pulled up and off the back of your head when you place both hands on the rear of the helmet and forcibly lift it.
If the helmet comes off or is on the verge of doing so, it is either too big or the chin strap is not tight. Keep trying until you find the perfect size.
WARNING: even for a short ride, do not lend your helmet if size is not well suited to the person using it.
