Therefore, when choosing a waterproof backpack, it is important to choose a bag with good waterproof performance, and of course, you can also cover it with a rain cover.

It is common to get caught by weeds and branches, or to rub against the walls and tree poles while resting on your back. If the waterproof backpack is of poor quality, it is easy to break.
Tear resistance of waterproof backpacks: When choosing a waterproof backpack, be sure to choose a waterproof backpack that is tear resistant; When traveling outdoors, all the tents, cooking utensils, and other items we bring are packed in backpacks. If the quality of the backpack is not good, half of the contents may be torn due to excessive force, or if the body cannot bear the weight of the contents during walking, it may cause tearing.
Nowadays, most waterproof backpacks use TPU bonded fabric or PVC mesh fabric, which are professional waterproof fabrics. The TPU adhesive fabric is made of one layer of TPU, with nylon in the middle and TPU coating in the other layer, which is of good quality and resistant to scratches and tears.
