When you are hiking or adventuring you probably want to keep your essentials, mobiles and other belongings away from water. So a waterproof backpack is the best choice. So do you know the difference between the ordinary backpack and the waterproof backpack? How to choose a best waterproof backpack? Read on please…
1. Material difference
The significant difference between a waterproof backpack and an ordinary backpack is in the choice of materials. Common materials are wet when exposed to water. Some materials are water repellent, which is coated in order to block the water. But it doesn’t work when it rains dogs and cats. However, the waterproof backpack is made of heavy duty and better performance materials.
2. Production technique difference
The production process of waterproof backpacks is more complicated than that of ordinary backpacks. Many fully waterproof backpacks need to be molded. The common ones are some hard shell backpacks. These all use the molding process, while ordinary backpacks basically only need to use traditional ones. The sewing process will do.
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 chooses ordinary zippers, which are not waterproof and breathable, while the zippers selected for waterproof backpacks are waterproof and exposed to water. It will not penetrate, and can protect the contents more effectively. There are several ways to open the mouth of a waterproof backpack: Generally, the mouth is rolled, that is, the mouth of the bag is folded and fixed with a buckle or other parts to achieve a sealing effect. The other is a bayonet-style sealed bag mouth, which is often used for small waterproof bags, and large waterproof bags are impractical. 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 bags, and waterproof waist bags.
