We often see different types of helmets in daily life, and there will be some differences in shape. Semi-helmets and full helmets of motorcycles are often used by us, and there are many types of helmets. If you want to buy a suitable helmet, you must choose it according to your needs. So what's the difference between these two helmets? The first difference is that the scope of protection is different A full helmet is a full-enclosed helmet, which has better overall protection effect and can also ensure good protection effect. The full helmet actually protects the whole head directly, so the safety performance is higher. However, the semi-helmet of motorcycle only provides basic protection, and the position behind chin and head is unprotected. Therefore, from the perspective of safety, the protective effect of full helmet is better, but the semi-helmet can only be used as basic protection. The second difference is that the vision is different From the perspective of vision, it is true that the motorcycle semi-helmet is better and comfortable when ventilated. If it is a slow ride, it is more suitable to use the semi-helmet. This can effectively increase the visual field area and ensure a good perspective effect. And don't worry about being particularly oppressed. Comfort and breathability are good. However, the application of full helmets on some roads with high speed and good road conditions will be better, but the vision will be narrower.
