Back to today's theme: Is this backpack waterproof?

Why are more than 90% of backpacks on the market not waterproof!

At present, whether it is a normal backpack or a mountaineering backpack, their manufacturing process is nothing more than fabrics, zippers, straps, buckles and other required components... through sewing. Because of function and production considerations, most backpacks have: a lot of sewing, zippers, and irregular structures.

There are some videos in the workshop that spray the backpack with water, and we will see water droplets slip off the fabric quickly, but we must honestly say that this water-repellent function is completely unable to withstand heavy rain or long-term rain!

because

1. Water-repellent function, its water pressure resistance is quite low and cannot withstand heavy rain or prolonged rain.

2. The irregular shape of the backpack will cause some water to accumulate in the ditch of the backpack. After a long time, the rain will definitely leak!

3. The zipper and stitch design of the backpack cannot withstand the invasion of water for a long time.

This is why more than 90% of backpacks, we dare not call it a waterproof bag. Because a backpack that cannot reliably block water for a long time, we cannot call it a waterproof bag!

And in a humid and cloudy environment, whether it is hiking or going out, we definitely don't want the items in the backpack to be wetted by rain, so how do we do proper waterproofing?

Generally speaking, we would recommend two direct methods to protect the items in your bag.

1. Use waterproof backpack cover: The waterproof backpack cover is like the raincoat of the backpack. We use the backpack cover to cover the entire backpack to achieve the waterproof function. When choosing the backpack cover, we need to pay attention to the size of the backpack and the size of the backpack cover. Suitable, in case the wrong size leads to poor fit and water leakage.

2. There is a bag in the bag: In order to add a layer of protection to the items in the backpack, we can also use the waterproof bag to add another layer of insurance to spare clothes, food, sleeping bags, electronic equipment, etc.

Waterproof backpacks on the market

On the market, there is a style of bag. We will have the courage to call it a waterproof bag. Although there is still a limit of underwater depth, this type of backpack can achieve better results through tarpaulins and scroll openings. For reliable waterproof ability.

We can use this kind of backpack for water sports, hiking, and tracing. Daily use can also cope with any heavy rain!

From this topic, we will specifically focus on the word waterproof and make a more clear explanation.

Generally speaking, we can define waterproof from three aspects

1. Completely waterproof:

To explain waterproof accurately, it should be an absolute term, which means that no water leakage will be caused at any water pressure, and our outdoor equipment needs more functions than waterproof due to some materials. Therefore, it is rarely completely waterproof.

2. Waterproof factor/grade:

Waterproof coefficient/grade is our definition and explanation of waterproofness on outdoor products. Because the waterproof coefficient/grade is different from complete waterproofing, it represents a difference in degree. For example, different rainfalls have different water pressures, such as the underwater depth of diving watches, etc., just like the waterproof coefficient we use in waterproof fabrics ( The waterproof coefficient of 3000mm means that the cloth will seep when it is pressurized with a water column of 3000mm pressure), or the IPX waterproof rating marked on electronic products, we must use these specifications to let us know the waterproof ability of our equipment, it Enough for us to use in what environment.

3. Water repellent:

It has almost a shadowy function in our equipment. The principle of water repellency is to make fabric or leather difficult to absorb water through hydrophobicity. In the case of heavy rain or heavy rain, it is the layer that will be broken the fastest, and the anti-splashing water will be lost with use, and spray/lotion must be used to maintain its effect.
