3. Differences in accessories

Regardless of whether it is a waterproof backpack or an ordinary backpack, the manufacturer's opening method is a zipper opening, which involves the choice of zipper accessories. The ordinary backpack also has an ordinary zipper, which is not waterproof and breathable, while the zipper selected by the waterproof backpack is waterproof. It will not penetrate in, which can more effectively protect the guaranteed items. There are several ways to open the pocket opening of the waterproof backpack: the roll opening is generally used, that is, the pocket opening is aligned and then folded and fixed with a buckle or other components, so as to achieve a sealing effect. The other is the bayonet-type sealed bag mouth, which is mostly used for small waterproof bags, and large waterproof bags are unrealistic. Another is the airtight zipper opening. The airtight zipper is also a waterproof zipper with a high waterproof level. This kind of zipper has a high cost and is generally used for advanced waterproof backpack openings, outdoor ice packs, and waterproof waist bags.
