Age group
—
For preschoolers. Models designed for the youngest age group — up to 7 years. They have a bright design, as well as small size and capacity — however, large volumes in this case are not needed. With such a backpack, it will be convenient for a child to go to a kindergarten or a preparatory group, inside you can put a change of clothes, drawing supplies, etc.
—
For schoolchildren. Backpacks designed mainly for children of primary and secondary school age — from 7 to 12 years. However, some models are suitable for high school students. They are more diverse in terms of equipment than preschool ones, often have more departments (both internal and external), and the volume can be very different — from a small one,
10 liters or less, to
30 liters or even more. This allows you to choose the best option in terms of size and volume, and as the child grows, you can also change the backpack from small to larger and more spacious.
—
For teenagers. Backpacks for teenagers aged 12 years and older, in fact — for high school students, and even junior students. They do not have such a “childish” design as the younger models, but they are still quite diverse, they can be discreet, and quite bright and colorful. The volume can also be different — from a few liters to 30 liters or more.
Capacity
The total volume of the product. It can be indicated both with external pockets and without them (see "Compartments") — this is not critical in this case, because the capacity of the pockets is small and does not really affect the overall capacity. But the external compartment (see ibid.) is necessarily taken into account in the characteristics, since it accounts for a fairly significant part of the volume.
Larger capacity allows you to carry more items inside. On the other hand, for pupils of primary and secondary grades, capacious backpacks are not required, and a heavy load can be harmful to health and normal development. Therefore, the volume largely depends on the age category. Thus, the volume of backpacks (see "Type"), which were originally designed for the younger age group, rarely exceeds 20 liters, and in most cases is less than 15 liters. The same applies to bags, but in their case it is more likely due to design features, and the volume is generally larger — up to 29 liters. Backpacks are the most voluminous — among them models of 25 liters are not uncommon, and in some
the volume exceeds 30 liters. However, the choice of volume depends not only on the age category, but also on the expected amount of cargo. So, a high school student may not need a roomy backpack if the school has lockers and textbooks are mostly stored there.
Compartments
Additional compartments provided in the design of the product (in addition to the main one).
—
External. Additional compartment with a separate fastener, located on the outside of the backpack (on the opposite side from the back). It can have different sizes: most often, the outer compartment occupies the entire height and width of the backpack, but in some models it is made in the form of a relatively small additional pocket. Anyway, this feature allows you to organize the contents of the backpack by placing it in the appropriate compartments: for example, you can keep textbooks in a larger compartment, notebooks in a smaller one.
—
Penal. A small outer compartment designed for any small things; the name "pencil case" hints at the fact that it is designed for pens, pencils, erasers and other stationery, but in fact you can hold any small items there. Thanks to this, they are not lost in the main compartment, and you can get to the contents of the pencil case quite easily and quickly. Moreover, an organizer can be provided inside — a set of pockets for stationery; however, in some backpacks, the organizer is placed in the main or external compartment. Do not confuse this function with a separate pencil case (see "Additional") — we are talking about the built-in compartment.
—
Bottle pocket. A separate pocket for carrying bottles an
...d other items of a similar shape — thermoses, umbrellas, etc. It is usually located outside, on the side end of the product, and is made in the form of an elastic mesh capable of "holding" the object placed inside. Often there are two such pockets, on both sides. The bottle pocket is convenient because you can get to its contents without opening the main compartments, and with a certain skill, even without removing the entire backpack: just remove one strap and put your hand behind your back. In some models, one of the bottle pockets is also regularly used as a seat for a complete pencil case (see "Additional").
— Side pocket. Like the pocket for a bottle (see above), such a pocket is located on the side end and there may be more than one. The main difference lies primarily in the form and purpose: side pockets are usually made for flat and/or small items. In addition, they are often equipped with zippers or other closing devices. The side pocket is usually not connected to the main compartment, it is convenient to store various small things in it, which can be “lost” inside the bag / knapsack / backpack, or which need quick access.
— Hidden pocket. A secret pocket, usually, is located on the back of the backpack. Thus, when the backpack hangs on the shoulders, the pocket is hidden from view and from access to the contents. This is especially convenient when carrying small valuable items, because. gives maximum protection against theft.
— Internal dividers. Partitions dividing the main compartment of the backpack into several parts. This design makes it easier to put the contents in order: for example, textbooks, notebooks and inventory for a labor lesson can be separated by partitions. At the same time, partitions are more convenient than the division into the main and outer compartments (see above): just open the backpack — and all the contents will immediately be at hand, you do not have to unfasten / fasten each compartment separately. Also note that one of the separators can block off a special seat for a laptop or tablet.Design
—
Rigid frame. The presence of a rigid frame is mandatory for knapsacks, but can also be found in backpacks. In knapsacks, it is used to constantly maintain the same shape, as comfortable and safe as possible from an orthopedic point of view. In backpacks, a rigid frame is used to protect the contents from impacts, especially side impacts.
—
Folding. Models that are able to unfasten to the very bottom and open like a book. Usually, the role of the lock in such products is played by a “lightning” that goes on top and on the sides of the backpack. The folding design makes accessing the contents more convenient and can make loading and unloading and searching for items inside much easier.
—
Orthopedic back. The back of a special "orthopedic" shape, thanks to which the load is distributed over the child's back in the most optimal and safe way. In addition, the surface of such backs is usually embossed, which improves ventilation and reduces sweating. Note that "non-orthopedic" backs can be quite comfortable.
—
Chest strap. Attachment in the form of a strap with a clasp that connects the main straps of the backpack at the level of the user's chest. When fastened, such a strap keeps the straps at the same distance from each other and does not allow them to “scatter”. This provides additional convenience in
...the distribution of weight, as well as a secure fit on the body.
— Waist belt. An additional device in the form of a belt, which, when fastened, covers the user's body in the belt area. Thus, the load is redistributed from the shoulders to the pelvic area, which is especially convenient when carrying heavy backpacks. In addition, such a device provides additional reliability of fixing the backpack on the body.
— Soft straps. In this case, straps are meant that have additional soft pads made of foam rubber or other similar material. Thanks to this material, as well as the increased width, such straps do not cut into the shoulders and remain comfortable even with a fairly large weight, and the load is distributed more optimally than on straps without pads.
— S-shaped straps. S-shaped shoulder straps (when viewed from the back of the backpack). It is believed that this form provides a more rational distribution of the load than the sickle-shaped, and even more so the classic straight line, it gives more freedom to the hands and prevents the backpack from slipping off the shoulders. In addition, S-shaped straps are easier to equip with chest straps.
— Rain protection. A device that protects the backpack (and its contents) from rain, snow and other natural “troubles”. Usually, it has the form of a “hood” or a cover made of waterproof material, which, if necessary, is put on top and provides additional protection. Note that almost any backpack / knapsack / bag is able to protect the contents from moisture to a certain extent; however, for maximum weather resistance, you should still choose models in which this feature is directly stated.
— LED backlight. The backpack is equipped with built-in lighting, which, usually, is represented by an LED strip located in a straight line. On the one hand, the backlight has a decorative effect and makes the backpack itself more attractive to children. On the other hand, it can act as an identification mark, for example, when crossing the roadway, and in general increases the visibility of the child on the road at night
— Reflector. Special reflective inserts, located, usually, on all sides of the product — for example, in backpacks and satchels they are installed on the straps, on the outside and on the sides. Such inserts brightly "flash" in the light of car headlights, making the child clearly visible to drivers in the dark. The features of night driving and vision are such that reflectors will not be superfluous even on a lit street, not to mention darker environments. And in some countries, traffic rules even forbid pedestrians to move at night without reflectors. Anyway, this feature can be very useful from a security point of view.Weight
Empty weight. This parameter has a dual meaning. On the one hand, the lower the own weight of a backpack, bag or knapsack, the less load will be on the shoulders of the child with the same weight of the load. On the other hand, with the same materials, a lighter product is also thinner and, accordingly, less durable.
