When choosing a helmet, you must choose the size that fits your head. This is obvious. However, how to choose a helmet that fits your head size is not that simple, especially now that everyone prefers to shop online.
Choosing the size of the helmet, whether it is L or XL, is not very important to us. Because each brand, and even each model of the same brand, has different sizes. If a certain brand and model of L size fits you, it does not mean that all helmets of L size will fit you. It is possible that another helmet of XL size will also fit you.
So we can’t just look at the size of the helmet, but we should see whether the head circumference marked on the helmet is consistent with your own head circumference.
How to measure head circumference? Please see the diagram from a Taobao merchant:
After getting your head circumference data, you can buy a helmet of the corresponding size online. Remember, add 1cm if you have a fat face, and subtract 1cm if you have a very thin face. Except for a few merchants with strange ideas, most merchants will mark the corresponding head circumference size of each size of this helmet under their helmets. Most helmet manufacturers, especially ECE standard helmets, will also mark the appropriate head circumference size on the helmet.
It is not so troublesome to buy in offline stores. After asking for the merchant’s opinion, just pick it up and try it on. The standard for trying on tightness is: after putting it on, shake your head left and right and up and down. If the shaking amplitude of the helmet and the head is inconsistent, it means that the helmet does not fit the head well and the helmet is too big; if the helmet fits the head, but it hurts or hurts near the temples on both sides, it means that the helmet is too small. If the helmet fits the head but does not hurt, then the helmet is suitable. Generally speaking, the larger the fit area of the helmet, especially the full-face helmet, with the head, the more suitable the helmet is for you and the safer it is. The ideal state is that all parts of the full-face helmet, except for the lenses, fit the head and face with appropriate tightness. This is the best.
Of course, if it is a little tight and you are not particularly uncomfortable even if you wear it for a long time, then you don’t have to worry at all. Because as the wearing time increases, the lining of the helmet will deform slightly, becoming more fit to your head and more comfortable.
Are European helmets not suitable for Chinese people? Friends often ask. ——This situation is common, because the head shape of most Westerners is different from that of Asians. Many Westerners have thinner heads, narrower left and right, and longer front and back, while many Asians have wider heads, and shorter front and back. Therefore, many friends who bought European and American brand helmets found that although the size was right, the fit was very poor. Then, congratulations, you bought a real European and American helmet!
Now, some helmet manufacturers have made some adjustments to this situation. They will develop different helmet models for the European and American markets and the Asian markets. For example, the following helmet:
The picture shows the head shape label on a European brand helmet. The black dotted line indicates that it is suitable for Western head shapes, while the yellow-green shape indicates that it is suitable for Asian head shapes. The English label below means: Suitable for Asian head shapes. Therefore, when we buy a helmet, if there is this label, we can just choose the label that is suitable for Asian head shapes.
In fact, there is a better way. We can directly choose helmets made by Asian brands for the Asian market. Such helmets have a better fit and are more comfortable. Japanese helmets, such as Arai and Shoei, are world-class brands with high safety levels, a wide variety of colors, and are comfortable to wear. The disadvantage is that they are relatively expensive. Some helmet manufacturers, such as Guangdong Jiangmen Pengcheng LS2 Helmets and South Korea’s HJC Helmets, have been OEMs for major European and American brand helmets or car manufacturers in the past. These manufacturers’ own-brand helmets are of good quality and high safety levels, but the prices are very cheap, which is very cost-effective.
Finally, here is a little trick for you: if you find that the helmet you bought online is one size too loose or one size too tight, if the lining can be quickly removed, you can first ask the merchant whether you can just replace the lining. This is because many adjacent sizes of the same model of helmet share the same size of helmet shell, the only difference is the thickness of the lining.
