There are two types of Laptop backpacks, one-shoulder Laptop Backpacks, and double-shoulder Laptop Backpacks. When we buy Laptop Backpacks, Laptop Backpacks provided by the merchants are single-shoulder Laptop Backpacks, but the mainstream Laptop Backpacks are double-shoulder designs.

Comparison of the comfort of one-shoulder Laptop Backpack and double-shoulder Laptop Backpacks.

We have learned about pressure in junior high school physics. Under the same weight, the smaller the force area, the greater the pressure! Therefore, from the perspective of comfort, a double-shoulder Laptop Backpack will be more comfortable than a one-shoulder Laptop Backpack, because the double-shoulder Laptop Backpacks will spread the pressure on the shoulders and back, while the one-shoulder Laptop Backpacks only gives one shoulder weight. Pressure.

Laptop Backpacks with two shoulders protect human health more than Laptop Backpacks with one shoulder.

Laptop Backpacks with two shoulders protect human health more than Laptop Backpacks with one shoulder. Because the pressure on the one-shoulder Laptop Backpack is on one side when carrying heavy objects, it is easy to cause deformation or damage to the spine. Over time, you will feel that one shoulder is unbearable. Therefore, the two-shoulder Laptop Backpack is the healthiest to the human body compared to the one-shoulder Laptop Backpack.

Features of Laptop Backpacks.

The double-shoulder Laptop Backpack can carry more heavy loads, and the capacity is much larger than the single-shoulder Laptop Backpack. When the laptop is not installed, the two-shoulder Laptop Backpack can also be used as a sports backpack or a travel backpack.

A Laptop Backpack with two shoulders protects the laptop better than a Laptop Backpack with one shoulder.

From the protection of laptops, a Laptop Backpack with two shoulders protects the laptop better than a Laptop Backpack with one shoulder. The reason is that the double-shoulder Laptop Backpack fixes the laptop on the back, which effectively reduces the collision of the laptop and reduces the sloshing of the laptop. The one-shoulder Laptop Backpack puts the laptop on one side of the body and cannot be properly secured.

The size of the Laptop Backpack should be matched reasonably.

Generally, a Laptop Backpack with a height of 17 inches and 30 cm diagonally (that can hold 15.6 notebooks) is recommended. However, if the Laptop Backpack has a large margin on both sides of the upper half of the space, it will seriously affect the assembly capacity. The Laptop Backpack is large, but it is not durable.

The foam sponge should not be too thin, otherwise, it will not be able to protect it. A good-quality Laptop Backpack will be placed close to the back of the human body in the computer mezzanine, and a relatively hard substrate is often designed to prevent the deformation caused by human activities from squeezing the computer. Low-end Laptop Backpacks are often stretched out in terms of cushioning performance. They will use some ordinary sponges as a cushioning protective layer, but this type of sponge is prone to moisture. Therefore, when you buy Laptop Backpacks, you need to focus on checking. If the sandwich area is thick and flexible, it is a good Laptop Backpack.

The waterproof capability of the laptop backpack.

A good Laptop Backpack will be made of materials with a certain degree of water resistance. In the selection of fabrics, the splash-resistant fabrics will ensure that the notebook will not be harmed in the face of light rain and spilled drinks. Laptop Backpacks produced by regular manufacturers have to be tested by water splashing, and the waterproofness should reach half a meter deep. In addition, considering that the bottom of the Laptop Backpack will be in contact with the wet ground, a good Laptop Backpack will be made of completely water-resistant materials at the bottom. Some Laptop Backpacks will also have a rain cover, a special waterproof compartment, etc., to maximize the waterproof capacity of Laptop Backpacks.

The sturdiness of Laptop Backpacks.

The quality of Laptop Backpacks depends largely on the material used. Different fabrics bring different feelings into use. A good-quality Laptop Backpack generally uses nylon or polyester fiber as the fabric. This is the best Laptop Backpacks fabric material at present, strong and durable. It can be waterproof and wear-resistant. Of course, there are also high-end Laptop Backpacks that use leather as the main material. The leather feels good, but it will increase the weight of Laptop Backpacks.
