What is a backpack for? And in order to free your hands and not be constrained in movements, as well as correctly distribute the load on the back. However, this statement is true for a well-made and correctly selected backpack, otherwise it will constantly fall off your shoulders, rub and cause discomfort. And, what is most unpleasant, can lead to curvature of the spine and even spoil the carried load or thing. For example, it is unlikely that the camera body will remain intact if keys are constantly rubbed against it. Therefore, the choice of a backpack must be taken as responsibly as possible.
It is recommended to pay attention to the trademark Demix. Its products have been pleasing to their customers for more than a decade. Their slogan is: "High quality at affordable prices." Buying a Demix backpack (people's reviews indicate the accuracy of the information), you get a 100% guarantee on the product from the manufacturer. It is worth noting that the range of these products is very large, so everyone can easily choose the necessary design, color and shape. But is it that simple? As a rule, a wide choice sometimes, on the contrary, complicates the task.
So, how to choose the right Demix backpack? First of all, it should be one with the human body and be practically imperceptible. It is undesirable to save on such a purchase. Any backpack is a purely individual thing, one might even say intimate, so we’ll try to understand the key points of the choice.
Special purpose
Most people often make the same mistake. It lies in the fact that they are trying to purchase a universal Demix backpack (see photo below), which would be useful for walking in the park, for hiking in the mountains, and for a trip to the country. For such purposes, there are different models. As a rule, they differ in material, shape and content. Such versatile backpacks will either burst at the seams from an overabundance of things, or hang out on their backs. Therefore, before buying, you need to decide what exactly it is needed for. And only after that stop your choice on a specific model.
Appearance
After determining the purpose of the purchase, you need to clarify for yourself how the Demix backpack should look. Based on the scope, it is possible to conditionally distinguish several types:
- Urban - a dense stylish backpack, the capacity of which reaches 20-25 liters. There are both male and female models. It can easily accommodate books, a laptop, a shock-resistant eyeglass case, folders for papers and other things.
- Assault - a convenient and small backpack with a capacity of 40-60 liters. This model is designed to quickly climb a mountain peak, so it has many awnings for equipment and pockets.
- Tracking - a backpack with a capacity of 50-80 liters, used for long trips and camping. This product is equipped with large internal compartments and external mounts for a thermos and rug.
- Expeditionary - the capacity of a backpack, considered an icon of tourism, is 60-120 liters. It is intended for long trips, it has the largest capacity, and its back and suspension system most evenly distributes the load throughout the back.
- Demix sports backpacks are roller, bicycle, ski, ski and others. A feature of such models is their small size and compactness. As a rule, they are intended only for the most necessary. For example, a bicycle backpack is equipped with a ventilation system for the back, and a skitur backpack designed for descent on boards and skis has a frame whose design supports the back in the event of a fall.

Choose size
One of the paramount values is the size of the backpack. It is determined by the following parameters:
- age of a person;
- level of physical fitness;
- the floor.
It is important to know that the Demix backpack should be fit. If you buy it with the prospect of increasing growth or muscle mass, then it will only cause inconvenience and will not be able to perform its tasks.
Optimal level of quality
When buying a backpack, you need to make sure the fasteners are secure, all locks are in good working order, moisture proof (if this is the product specialization), and the integrity of all seams.
The full potential of a backpack is revealed when it is chosen correctly. After all, a high-quality product should not be an ordinary bag behind you, but a competently designed assistant in everyday life. Only a well-chosen Demix backpack can become a faithful and reliable companion for many years.
