At present, the helmets that consumers can buy on the market are roughly divided into four categories: half-cover, three-quarters, full-cover hood (opening cap) and full-face helmet. . Half-cover helmet, also known as melon cap, is the most common type of helmet on the street. It has the advantages of small size, good wear and tear, good storage, etc. The disadvantage is that because of its small size, the protection range is quite limited, and it may be caused by external force when an accident occurs. The helmet is detached and the head cannot be protected. From a safety perspective, it is not recommended to purchase this type of cap. The three-quarter helmet is part of the half-cover type, but the protection is much better than the general melon cap. The advantage of the three-quarter helmet is that it can give the head better protection and covering, and the volume is much larger than that of the half-hood helmet. Most of the three-quarter helmets have ventilation design. It can take away the sultry feeling of wearing a safety helmet, and the shortcomings are not fully covered. Some models extend the lens to the lower jaw for basic protection. It is easy to cause damage to the lower jaw when an accident occurs. At present, only Arai The SZ-Ram series and MZ are certified by Snell to provide a protective effect similar to the full cap. The face-opening cap and the full-face helmet are similar in type. The front armor is designed to be movable and can be lifted up with the lens to facilitate the capping and replenishing of the cap, taking into account three-quarters of the cap. Convenience and safety of the full cover, because the lifting action is similar to that of the soda water pull-tab when it is pulled up, it is commonly known as a soda cap or a cola cap, but its disadvantage is that it is designed with a movable face, the overall cap weight even exceeds A full-face helmet is more prone to fatigue when worn for a long time. The full-face helmet can completely cover the head and provide the best protection. For most racing competitions, for the safety of the driver, it is required to wear a full-face helmet that meets the requirements. There are disadvantages such as difficulty in wearing and unloading, and difficulty in storage, especially the full-cover design, which generally makes the wearing knight's head feel more stuffy, but the manufacturer has always done a good job on the ventilation system of the cap body. When you greatly reduce the discomfort, based on security considerations, we recommend that you try to choose such a helmet. After deciding which type of hat to buy, the budget should be another very important factor. In general, there are several factors that determine the price of a hat, including the type, imported or domestic, color, and even the body material. The type has been introduced in the previous unit. The principle is that the full-face cap has the highest price, followed by the cola cap, three-quarter cap and half cap. For domestic brands, full cap or uncovering The helmet is about 300 yuan to 800 yuan, and the three-quarter hat is about 200 yuan to 400 yuan. In addition to domestic brands, there are many imported brands on the market. For example, Arai, Shoei or AGV, which everyone is familiar with, are basically four-digit prices. In fact, whether it is domestic or imported hats, As long as the cap is certified by the same regulations, it is safe in terms of safety. Most of the high-priced imported hats are undoubtedly comfortable in terms of comfort and safety. The performance of domestic caps is gradually improved and developed by manufacturers. The wearing comfort and assembly quality are gradually approaching. The knights can follow their own. The ability to choose products without the need to pursue imported brands. The material of the cap is an important factor in determining the price. In addition to the ABS materials currently available on the market, there are also higher-order composite material caps, which are lightweight and high-strength using kungfu dragon fiber, carbon fiber, etc. The material, also has the PB-SNC2 material developed by Arai. It has different names according to the different research and development techniques of various manufacturers, but basically it is used in high-end caps. It is called a penny, a composite material. It is much lighter than the ABS material, and the price is much higher. Each helmet has different characteristics, uses and added value, often around the choice of consumers, the color is also very important, the helmet will basically launch a plain color, if you want more style, or reduce on the road If you hit the color probability, you can choose the "painting model", because the life of the helmet product line is long, and it can't be updated every six months like the 3C product, so the manufacturer will do more on the cap color, most manufacturers will also The paints of the limited editions of the year were introduced for consumers to purchase. In addition to safety, you should also pay attention to the comfort associated with daily wear, while the inner lining is the part of the helmet that is closest to the skin. When purchasing a helmet, pay attention to the material of the lining. Breathable design, Xiaobian reminds everyone that the helmet lining is a need to clean regularly! If not cleaned regularly, it may cause inflammation of the hair follicles and fall. When choosing a lens, please pay attention to whether the lens has anti-UV [UV], and do not use dark ink film or electroplating film with stronger sunshade ability at night. Due to insufficient light transmittance, the driving line of sight is not good, but in recent years Many safety helmets have built-in ink film system, which is usually stored in the cap body. When necessary, the ink sheet can be pushed out. Some brands even introduce color-changing lenses, but the unit price is also quite high. In addition, some caps in the current market have extended some safety-increasing or style-like accessories, such as quick-release shackles for three-quarters of helmets, or detachable visors. Adding off-road atmosphere gives consumers more choices.
