To know what helmet size you are, you must measure the circumference of your head. For this you can help yourself, for example, with a measuring tape or a thread. Once that value is obtained, you will find your corresponding size in the following table.
SHELL SIZES
Most helmets have two shells (outer part) for the entire range of sizes. If there are more shells, you can wear one that is more suited to the circumference of your head without having to carry the weight and size of one that is excessively large for you.
| ADULT SIZES | HEAD CIRCUMFERENCE |
| XXS | 51-52 cm |
| XS | 53-54 cm |
| S | 55-56 cm |
| M | 57-58 cm |
| L | 59-60 cm |
| XL | 61-62 cm |
| XXL | 63-64 cm |
| 3XL | 65-66 cm |
| 4XL | 67-68 cm |

SECURITYÂ System
To ensure good protection the helmet must fit your head to perfection, special attention should be paid to the shell shape design and materials to minimize the effects of a possible impact. It is key to obtain a perfect fit to your head from outside to inside, as well as the shell, the configuration of the EPS liner, which should match closely the human head shape.
