The main function of knee pads is to provide support and protection for the knees. In outdoor sports, especially high-intensity activities such as mountain hiking and long-distance running, the knees bear tremendous pressure and impact. The knee pads are made of highly elastic materials, which can tightly fit the knee, providing stable support for the knee, reducing vibration and impact caused by exercise, and reducing the risk of knee injury.

Knee pads also have warmth and protective functions. In cold weather, knee pads can block the invasion of cold winds, keep the knees warm, and avoid muscle stiffness and pain caused by the cold. At the same time, knee pads can effectively prevent scratches and impacts from external objects such as sand, stones, and branches on the knee, protecting the knee skin from damage.
