If you are engaged in long-term exercise, it is best not to choose to carry your backpack for a long time. After all, carrying it for a long time is not good for your body. Try to carry it by hand after one or two hours and then put it back on. This way, you can balance work and rest with your backpack, which can greatly extend its lifespan.Secondly, you should frequently expose your bag to the sun and not keep it indoors without engaging in outdoor activities. Without the nourishment of sunlight, your bag may develop mold and produce some unpleasant odors, making it very uncomfortable to smell. Moreover, you have to carry it on your back. So, why not take out your love bag for a sunbath every once in a while to give it some sunshine?Thirdly, try to avoid significant friction. During use, it is inevitable to encounter some wear and tear. This does not mean that wear and tear cannot be avoided, but rather that efforts should be made to minimize the damage caused by wear and tear, and to take care of yourself with less wear and tear. Try to avoid using it in areas with high friction or uneven surfaces. If it is necessary to use it, be cautious and do not engage in direct friction unless absolutely necessary.
