When it comes to waterproof backpacks, many people immediately think of mountaineering bags with a rain cover. In fact, the main bag of a real all waterproof backpack is made of high-frequency welding, which can not be achieved by sewing.

What is full waterproof? What are the grades or categories of waterproofing? Full waterproof, that is to say, at least ipx7 or above can be considered as fully waterproof, that is, the waterproof level of more than 15-30 minutes of soaking in the water for more than 1 meter deep without water inflow can be considered as full waterproof. And full waterproof is light waterproof, that is ipx5-6 grade, instant soaking water, lifting out, no water. Further down is the waterproof level of rain proof, that is, the waterproof level of a rain cover to solve the problem. For example, the rainproof level of mountaineering bag is that there is no water in the rainstorm for 10-15 minutes. And then down is the life waterproof, that is, the water-proof anti sprinkling, anti rain level waterproof.
