I have been using SUOMY for a long time, and I bought it because I like the design I am very satisfied with it However, the hook of the chinstrap broke when I was hanging it on the Helmet holder I am not happy with that part, but if I have the opportunity to buy it again, I will definitely buy it Thank you

Size Chart For Helmet
How to measure the size of your head
First, measure the circumference of your head with a measuring tape.
Measure from the highest point of your forehead, just above your eyebrows, horizontally backwards to the highest point of the back of your head and around.
Based on the measurement, choose the size from the table below.
However, unlike hats, helmets cannot be sized by head circumference alone.
Also, helmets of the same manufacturer may feel different even if they are the same size depending on the model.

Ordering Size | XS | S | M | L | XL | 2XL |
Head Measurement (cm) | 53 - 54 cm | 55 - 56 cm | 57 - 58 cm | 59 - 60 cm | 61 - 62 cm | 63 - 64 cm |

Especially, SR-SPORT has many kinds of pads with different thickness, for example, it is possible to make the size between S and M, or M for head circumference and L for cheek.
[outer shell]
The outer shell is made of SUOMY's own special fiber called TRICARBOCO.(excluding ROKK)
TRICARBOCO is a combination of three types of fibers: KV, which has high tensile strength, carbon, which is light and strong, and aramid, which has high impact penetration strength.
The shell is stronger than full carbon alone, lighter and stronger than FRP alone, and the Japanese special version is even stronger than the SG standard which is stricter than other countries.
Carbon model is made by making the best use of carbon material and supplementing strength by TRICARBOCO, which is ideal specification for racing helmet.
