Do not drink all at once during exercise, because drinking a lot of water in an instant can easily cause a huge burden on the heart. Scientific research has found that the way to replenish water when people are exercising is to add 100 ml of water every 15-20 minutes. However, if a traditional water bottle is used to hold water, it is difficult to guarantee this frequency. The water bag is equipped with a 100CM long soft drinking water tube, which is convenient for drinking water even if it is placed in a backpack. Small amounts of water made easy.
