2. When running, you must sweat a lot. If you feel uncomfortable wearing underwear, wearing tights directly can prevent friction. But if the tights are not clean enough, it is best to wear a pair of underwear when exercising. When exercising, if you choose underwear, you'd better choose briefs. If it is boxers, the thighs will be lifted repeatedly during running, the lower edge of underwear will be rolled up, and the pressure of tight pants or compressed pants will affect comfort. If you wear briefs, you can avoid curling your underwear. Whether you wear underwear or not, you should pay attention to the cleanliness of your private parts to avoid bacterial infection.

3, sports tights are made of special fabrics, and there is no sense of restraint when worn on the body. Feel light when exercising, and reduce muscle fatigue. When running, the muscles on the legs will shake violently. After wearing tights, it will reduce muscle jitter, and also reduce the energy consumption of the body to a certain extent and maintain physical strength. Tights have a good sweat absorption effect and can also have the effect of quick drying. During running, the surface structure of tights is larger than that of ordinary pants, and the water evaporates quickly, so they sweat faster and are more comfortable to wear.
