1. The two main performance indexes of the jacket are the waterproof index and the breathability index. Only the jacket that meets the requirements is the real jacket.
2. The waterproof index usually needs to reach more than 6000mmH2O, and the air permeability index should reach more than 5000G/M2/24H.
3. The significance of these indicators in practical use is that if you are in a severe rainstorm environment, functional clothing can ensure that you will not be wet by the rain, thus causing loss of temperature due to the water chill effect.
4. It won't make you wet in the ice and snow environment.
5. And when you are exercising a lot, your sweat can be quickly volatilized, so as to keep your body dry and give you a warm and comfortable microclimate.
6. In order to make the functional requirements of the jacket meet the needs of various sports, the surface moisture resistance, hydrostatic pressure, and moisture permeability are divided into grades I and II in the standard. The requirements of grade I are professional sports requirements, and grade II is general. Sexual outdoor sports requirements, level I is relatively stricter than level II.
