Kneepad effect

Knee pads have three functions, one is braking, the other is heat preservation, and the third is health care. Not much to say about heat preservation. The knee is very easy to catch cold. Many knee joint diseases are related to cold knees, especially in the mountains. 

The mountain wind is very cold and hard. Often the leg muscles will feel very hard due to constant exercise. The knee is not hot because there is no muscle movement. When people feel that the heat dissipation of the leg is very comfortable, the knee is actually getting cold. 

At this time, if you are wearing a knee pad, the heat preservation effect of the knee pad can be reflected.
