The shell and hat body have better fit and stronger strength to better protect our heads.Non -type molding means that the foam is formed first, and then the PC or PVC suction shell is put on the foam.The strength is relatively weak.But the price is cheaper.

2. Shell texture

cycling helmet shells are usually composed of PC (polyethylene) or PVC (polyvinyl chloride). The integrated helmet made of PC material is durable and cold -resistant.PVC material is not cold -tolerant, and has poor thermal stability and impact resistance. Whether it is rigid or soft PVC, it is easy to produce brittleness, poor use, and the safety factor is not high.Generally, the integration of PCs is better, the texture is better, it feels more real, and there is no gap.

It is better to be soft, tough, not hurting the Skin, and not allergic.

6. Adjustor

The regulator is used to adjust and fix the helmet, and it is also a critical accessory. The regulator is plastic. Generally, it depends on whether it can resist high or low temperature.It is likely that it is likely that high temperature or low temperature will easily break.

7. Belt ring buckle

Pay attention to whether the fastening method of the band ring buckle is Smooth and stable.So as not to clip or break easily, of course, loosening is also very easy to be fast, avoiding rough and sharp corners to cut the Skin.
