Attachment to a suitcase. The presence of a special belt that allows you to attach the backpack to the handle of the suitcase, thereby facilitating transportation.
— Elastic cord. Elastic cord attached to the front of the backpack in special loops. The main function of this part is to carry large items that do not fit in a backpack or that need quick access. For example, using a cord, you can fix a mat, bike helmet, jacket, etc. In addition, this function can be useful for more specific tasks — for example, drying washed clothes on the go. And in some models, the cord also works as an addition to the ties: by tightening it, you can seal the backpack that is not completely filled, reducing its size and not allowing the contents to hang out inside.

Mount for skis. A special mount that allows you to securely fasten skis to a backpack. If you are going to use a backpack in winter, it may make sense to pay attention to the presence of this item of equipment.
— Mount for the board. A special mount that allows you to securely fasten a snowboard or skateboard to your backpack. The specific specialization should be clarified separately, however, anyway, this feature greatly simplifies the transportation of the "board" — it does not need to be carried in the hands, while the fixation is very reliable. Usually, the mount can be adjusted to the size of a particular board.
...— Helmet mount. Special fastening for a protective helmet. Most often, such a mount refers to the LidLock system, designed for bicycle and other similar helmets that have holes in the shell. The main element of LidLock is a plastic plate on an elastic strap: such a plate is threaded into the hole of the helmet “sideways”, and then installed across the hole and, due to the elasticity of the strap, keeps the helmet on the backpack.
— Loops for equipment. Loops designed to secure special equipment, for example, "ice" — ice axes or walking sticks. Most often located on the sides of the backpack and can be adjusted in size.
— Folding chair. An original function characteristic of easel-type backpacks, designed primarily for hunting and fishing. The frame of such backpacks is used for its intended purpose during transportation, and at stops you can remove the bag and unfold it, turning it into a seating device.
— USB interface. Standard USB connector located on the outside of the product. Allows you to charge smartphones, tablets and other gadgets without unpacking your backpack — the main thing is that you have the appropriate cable at hand. Of course, for such charging, you will need a power bank or other source of energy connected to the USB port from the inside; such a source is usually not included in the delivery set.
— Mini-Jack connector (3.5 mm). A standard 3.5 mm mini-jack audio jack is located on the outside of the backpack, in some models right on one of the straps. From the inside, you can connect a smartphone, media player or other similar signal source to this connector, and headphones or portable speakers from the outside. Thus, this function allows you to listen to music without getting into your backpack once again and without taking the signal source out; this is especially convenient if a large gadget such as a tablet or laptop plays the role of a playback device.
— Raincoat included. A raincoat is a waterproof cover made of thin fabric worn on a backpack as additional protection against moisture during rain or snow. It is worth noting that most backpacks are initially made of water-repellent materials that can withstand precipitation to a certain extent. Therefore, it is especially worth looking for a model with a rain cover in the kit if there is a chance during a hike to get caught in heavy rain or stay in a damp atmosphere (fog, drizzle) for a long time.
— Reflective elements. Additional inserts on the outside of the backpack, made of a special reflective material. Such elements are located at least on the straps and on the front of the product, but can also be provided from the sides. Their main function is to make a person more visible on the road at night. So, in the dipped headlights, the driver notices a pedestrian in ordinary clothes for 20-50 m (depending on the colour of the clothes), and if there are reflectors, this distance increases to 100 m or more. Thus, reflective backpacks greatly increase safety on the road; and in some countries the wearing of reflectors is even mandatory for pedestrians at night.—
Compartment for a laptop. Compartment dedicated to transporting laptops. Usually, it looks like a separate compartment with dense soft walls — thus, the laptop inside does not hang around the backpack and receives additional protection from shocks and shocks. Note that different models with this function may have different restrictions on the maximum diagonal of the laptop (see below); therefore, before buying, it's ok to check whether the backpack will be compatible with your device.
—
Top pocket. The presence of a separate upper pocket, most often on the valve. In such a pocket it is convenient to keep relatively small but important things to which it is desirable to have quick access: a flashlight, a first aid kit, a map, etc. Also, this compartment can be useful for fragile things, because. Due to its location, it is slightly susceptible to impacts and concussions. For better protection, it can even be dense (hard).
—
Front pocket. The presence of a pocket on the "outer" side of the backpack (opposite back). The purpose of such a pocket is generally similar to the top one, however, in many models its design is such that it is most convenient to put flat things inside — documents, books, etc. In urban backpacks, the front pocket can also be called an additional compartment, fenced off from the main wall and having its own fastener.
—
...="/list/74/pr-36945/">Crab pocket. A detail that is not so much a pocket as a mount of a special design. In general terms, it can be described as a piece of fabric attached to the front of the backpack with elastic bands and/or fastex straps. Under this piece of fabric, the contents of the “crab” are placed, which is securely fixed by tightening the straps. In this way, it is very convenient to carry relatively large and pressure-resistant items that need quick access — for example, a jacket, a hat with a scarf, a bicycle helmet, etc.
—
Side pockets. The presence of pockets on the sides of the backpack. Their general purpose is the same as for any individual pockets: the placement of relatively small things that you want to have quick access to, or that can be "lost" in the vast space of the main compartment. Like the front ones, they are not recommended for fragile things. Unlike bottle pockets (see below), classic side pockets are made of dense fabric and usually have the ability to fasten.
—
Bottom pocket. Like the front pocket (see above), such a pocket is located on the front side of the backpack, however, it is located in its lower part, near the bottom (in fact, some models have both a front and bottom pocket). Another difference is the size: the bottom pocket is relatively small and is intended more for every “little thing” than for large flat items. And in some models, the role of the lower pocket is played by a part of the main compartment, separated from the rest of the volume by a partition; such a partition can be made unfastened, which allows, if necessary, to combine the lower pocket with the main compartment, and use the fastener of this pocket for lower opening (see "Design"). Anyway, the lower part of the backpack is most susceptible to shock and compression, so it is not recommended to store fragile items in it.
—
Weapon pocket. Pocket for carrying firearms. Usually, it is located on the outside of the backpack and is used to “hide” the butt of a long-barreled weapon. It can be supplemented with couplers for fixing the trunk. Also, this term means the presence of a pocket with a holster or an adaptive pocket for a particular type of weapon (for example, a pistol or a submachine gun).
—
Bottle pocket. A variation of the side pocket (see above), without a fastener and open at the top. The role of the latch is usually played by an elastic band in the upper part of the pocket, and the pocket itself can be made of mesh. In such compartments it is convenient to keep not only a bottle, but also other things of a similar shape that need quick access — for example, an umbrella. Also note that such pockets are convenient to use in combination with side ties; see "Cables and straps" for more details.
—
Pocket on the back. Pocket located on the back of the backpack. Designed for small but valuable items such as money or documents. The convenience of such a pocket lies in the fact that it can be reached only by removing the backpack; Thus, while the backpack is on your shoulders, you can not be afraid that an attacker will quietly unfasten the clasp and steal valuable contents.
—
Pocket on the waist belt. A separate pocket located on one of the halves of the waist belt (see "Cables and belts"). Usually can be fastened tightly. The volume of such a pocket is very small, but it has an important advantage: you can quickly and easily get to the contents without removing the backpack and without even unfastening the latches on the ties (whereas in other pockets this may require some skill or even outside help). This makes the waistbelt pocket perfect for small items that you need to have constant access to while on the move, such as a phone or a compass.
—
Webbing pocket. A pocket located directly on the strap — usually in the user's chest area (when carried in the normal position). Similar to the pocket on the waist belt described above, it is designed to store small things that you want quick access to (flashlight, food bar, etc.); however, this pocket is usually made open and differs in shape — it is usually high and narrow, under the shape of the strap itself.
The maximum diagonal of a laptop that can fit in the corresponding compartment of the backpack. Note that the average (standard) diagonal for modern laptops is 15.6", and most backpacks have
a 15" laptop compartment. However, there are also more voluminous models that can accommodate a
17.3" or even 18.4" laptop. At the same time, compact models are also presented: there are
backpacks with a compartment for a laptop 14",
13" and even smaller.
Note that the
lack of a laptop compartment in itself does not prevent using a backpack to carry a laptop, however, in this case, the maximum allowable size of the device will have to be specified according to the dimensions of the backpack.
