Key points for choosing jackets

Fabric of Jackets:

Charge jackets can achieve the goal of “letting out the water vapor inside, but not letting in the water outside”, mainly relying on the fabric material.

Generally, ePTFE laminated microporous fabrics are the most widely used because they have a layer of microporous film on their surface, which can simultaneously intercept water droplets and discharge water vapor. They have better waterproof and breathable properties, and they also perform more stably in low temperature environments.

Waterproof index:

During outdoor activities, the worst thing we can handle is the weather conditions, especially in mountainous areas where the climate is more complex and can lead to sudden rain and snow. Therefore, the waterproof performance of the diving suit is very important. We can directly look at the waterproofing index (unit: MMH2O), and the higher the waterproofing index, the better the waterproofing performance.

At present, the waterproof index of mainstream jackets on the market will reach 8000MMH2O, which can basically resist small to heavy rain. The better jackets can reach more than 10000MMH2O, which can easily cope with rainstorm, snowstorm and other severe weather conditions, and ensure that the body is not wet and very safe.

Recommend everyone to choose a submachine jacket with a waterproof index ≥ 8000MMH2O, the inner layer is absolutely not wet, and the safety factor is high.


Breathability index:

The breathability index refers to the amount of water vapor that can be released from a fabric of 1 square meter within 24 hours. The higher the value, the better the breathability.

Breathability is also an important factor that we cannot ignore when choosing jackets, as no one wants to sweat and stick to the back after high-intensity hiking or hiking, which can be stuffy and hot, and also affect wearing comfort.

We mainly see from the breathability index (unit: G/M2/24HRS) that a jacket with a higher breathability index can ensure that the water vapor on the skin surface is quickly expelled from the body, and the body will not feel stuffy, resulting in better breathability.

A typical jacket can achieve a standard breathability level of 4000G/M2/24HRS, while a better sprint suit can even reach 8000G/M2/24HRS or above, with fast sweating speed and can meet the needs of outdoor high-intensity sports.

It is recommended that everyone choose a breathability index ≥ 4000G/M2/24HRS for qualified breathability.

Misunderstandings in jacket selection

A good jacket not only needs to have strong waterproof and windproof performance, but also needs to have strong breathability. Therefore, the selection of jackets is also meticulous. When buying a sports jacket, it is important to avoid these misconceptions.

1. The higher the waterproof index of the jacket, the better it is. A good waterproof effect represents poor breathability. And the waterproof ability can be solved by brushing a coating, and high-end fabrics are both waterproof and breathable.

2. The same jacket fabric is not as advanced as better, different fabrics are suitable for different outdoor environments
