1. Service life: When buying a helmet, you should confirm whether there is relevant certification. In addition, you should also remember to pay attention to the service life of the helmet, which is usually 3-5 years (the service life of helmets made of different materials is also different). If the helmet is impacted by external force, although its appearance is not damaged, the internal cushioning material has been deformed and cannot provide effective protection, please do not use it again.
2. Ventilation: The helmet will come into the market only when it has practical effect after actual wind tunnel test. Some manufacturers also have a mirror demisting design, such as the Free Flow System, which integrates the design of the opening above the lens, the jaw opening and the neck deflector. When the jaw opening is opened, the fog on the mirror can be successfully taken away, greatly improving the demisting efficiency.
3. Lenses: High quality lenses are of safety design, not only not easy to break, but also will not break, that is to say, no matter how twisted, bent or hit, more of them will crack and will not break. There is no need to worry about being cut by fragments, and the lenses themselves are 3D shaped, not very thick, so there is almost no image dispersion.
4. Lining: Each helmet pursues a comfortable lining, which usually includes a main pad above the head and ear pads on both sides of the ears. A good lining not only helps the head and helmet fit together, but also has the shock absorption function. Most high-quality helmet liners can be dismantled and washed if they are dirty, and they can also be bought and replaced in different thicknesses to achieve a helmet that really suits your face shape.
5. Straps: When we wear helmets, we must not be careless or lazy without fastening the safety buckle of the straps. High quality helmet straps have passed strict pull tests. The double D-ring fixing buckle is a relatively safe safety buckle at present. Only by fastening it can the tragedy of helmet flying out in case of accidents be prevented.
6. Size: When purchasing a safety helmet, you should first measure your head circumference, and obtain the result size by measuring the area above the eyebrows and the wider part of your head. New helmets are usually a little tight. It is normal to pinch your face and cheeks. If you feel obvious pressure on your temples and top of your head, it will be smaller. Wearing a small helmet for a long time will cause headaches. It is better to shake your head from side to side without obvious shaking of the helmet. If the shaking test helmet is too large, the oversized helmet will not only leak air during driving, but more importantly, it will shake violently when driving at high speed, and it will also start to be effectively protected when the situation occurs. Helmets are more important safety equipment, and appropriate size must be selected.
7. Patterns: helmet manufacturers are constantly introducing new patterns with style and characteristics. In addition to passing the inspection, patterns also represent fashion indicators. For beginners, it is recommended to buy bright helmets that are eye-catching. Please avoid using paint or spray paint by yourself. Many paints are corrosive. Please use clean water or special detergent for helmet cleaning.
8. Cleaning: According to the survey, 75% of motorcycle riders do not have the habit of cleaning their helmets. They sweat when riding, and the interior is not easy to ventilate, which is easy to breed bacteria. The riders who wear unclean helmets may cause scalp diseases. When the weather is sunny, remember to put the helmet upside down in the sun. Some knights use water to clean the helmet lining, and pay attention to timely drying and drying. Now many knights will choose a special helmet cleaner to clean the helmet more quickly and effectively.
