1- In terms of applicability: non-professional, suitable for novices, just riding a rider;
The one-piece helmet can basically be regarded as a professional-grade riding helmet.
2- In terms of safety: the safety performance of non-integral helmets is much worse than that of one-piece helmets.
Although it can also play a protective role, it does not last long and is easily damaged.
3- In the workmanship: the non-integral helmet is rough, the PC shell and the EPS foam are separated, glued together, and easily cracked, so the rider who bought this helmet has cracked after receiving the goods. Please do not return, this is a very normal situation;
The one-piece helmet is made of high-grade materials whether it is a PC case or an EPS foam, and it is integrally molded and not bonded.
4- In the warranty: Because the non-integrated helmet is particularly easy to damage, it is generally not guaranteed. If it is due to express delivery, it can be inspected before signing, and the store is responsible for the replacement. If it has been signed, it will not be returned.
