Comparison HP Classic Backpack 15.6 18 L vs Continent BP-001 22 L

The working volume of a backpack determines the maximum amount of cargo that can be carried in it. Note that not all manufacturers indicate this parameter in the same way: in one case it can only be the volume of the main compartment, in the other — the total capacity, taking into account all compartments and pockets. If the exact value is important for you, you should separately specify this parameter for each model of interest.

The optimal volume of a backpack is directly related to its intended purpose and features of use. For example, for an urban model designed for documents and textbooks, most often 10 liters is enough, and for trips lasting several days, about 60-70 liters, or even more, may be needed. In general, when choosing the optimal volume for a hiking backpack, it is best to turn to reference literature, or for advice from experienced “hikers”.

Note that the volume of the backpack can often be adjusted. One of the options is side ties (see "Design") to change the thickness. And in some versions, it may also be possible to change the volume due to a special folding insert made of fabric — if necessary, it can be expanded and the height of the backpack can be increased. The names of such models often contain two numbers, for example 35:45 — they indicate the volume in the folded and unfolded form, respectively. In our catalog for these options, the maximum volume is indicated, in the unfolded position.

— Anatomical. The most common type of back in today's backpacks. In accordance with the name, the shape and design of such a backrest is designed taking into account the anatomy of the human body; thanks to this, the load is optimally distributed on the user's back, which allows you to carry significant weight without much inconvenience and harm to health (of course, if the backpack is properly selected and configured). The specific features of such backpacks can be different, but most often the back has protrusions and curves, which give it the necessary properties.

— Easel. This type of backrest is a one-piece structure in the form of a frame with straps (usually metal), on which the actual soft bag for things is attached. Easel backs are less comfortable than anatomical ones, so they are relatively rare, mainly in two categories of backpacks. The first is hiking models (see "In the direction") of large capacity, from 60 liters and above; in them, the soft bag is often made removable, which allows, if necessary, to hang another load on the frame that is suitable in size and weight. The second variety is backpacks for fishermen, where the frame is actually a folding chair (see "Equipment").

— Hard back. The presence of a rigid frame in the design of the backpack. Note that this feature should not be confused with the easel back: a rigid frame usua...lly means one or more metal plates built into the anatomical back. The main function of such plates is to optimize the load when the backpack is unevenly filled or when carrying hard objects of an “uncomfortable” shape. Without hard inserts, the contents of the backpack could press on certain points of the back, creating discomfort, and the plates evenly distribute all the pressure on the back. At the same time, in many models it is possible to remove the frame — for example, to reduce the weight of the backpack.

— Back ventilation. This feature suggests that the back has a special design that improves air circulation between the backpack and the user's back. This, in turn, improves thermoregulation and reduces sweating. Such properties are usually achieved through the use of porous breathable materials, as well as a special relief shape of the back itself. Note that this feature will be useful not only in hot, but also in cool weather.

— Adjustment of a back on height. The ability to adjust the back of the backpack in height is found only in models equipped with a waist belt (see "Cables and belts"). The essence of this adjustment is that, thanks to a special fastening, the main straps can be moved up or down, changing the distance between these straps and the waist belt. This gives additional features for adjusting the backpack to the height and physique of a particular user.

— 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: it is almost impossible to remove the backpack without unfastening the strap. To adjust to a specific user, the chest strap is often made adjustable.

— Adjustment of the chest strap. The ability to adjust the height at which the chest strap of the backpack is located. This function allows you to choose the optimal location of the screed, taking into account the height and physique of the user; while the range of adjustment is usually quite extensive. However in some models (especially inexpensive ones), adjustable ties can spontaneously move when accidentally touched, knocking down the height settings; however, this shortcoming is usually not critical.

— Top straps. Tie-down straps located at the top of the backpack. They are mainly intended for fixing the upper valve, as well as for adjusting the volume of the upper part of the backpack, similarly to the side straps described below (moreover, such adjustment can also be provided in models that do not have a valve).

— ...="/en/list/74/pr-9674/">Side straps. Tie straps located on the sides of the backpack — usually one on each side, however, in large tall models, there may be two on the side. The main function of such straps is to “compact” the backpack if it is not completely filled: by tightening the side ties, you can reduce the thickness of the backpack so that the contents are tightly fixed and not dangling inside. In addition, the side tie is convenient to use in combination with the bottle pocket for carrying long items, such as an umbrella or a mat: the lower part of such an item fits into the pocket, and the upper part can be fixed with a tie.

— Front straps. If the purpose of the ties described above is primarily to adjust the volume, then in the case of front ties they can be described as an additional fastening for placing things. They are two horizontal "belts" at the top and bottom of the backpack, under which you can fasten outerwear (similar to the principle with an elastic cord), a mat or other voluminous things, such as a snowboard. However, for the latter, these ties are not specialized and storage of the board in them is less convenient than in personal mounts. Naturally, the screed also fulfills its main function — it tightens the walls of the backpack, making its shape more “slender” and compact.

— Bottom straps. Tie-down straps located on the underside of the product. They allow you to adjust the volume of the lower part of the backpack (or the lower pocket), provide additional support and fixation of the contents, and in some models they can also be used as a fastener for carrying various items “on an external sling”: for example, you can put ties into stretched to the maximum size karemat and tighten the straps, securely securing the outer load.

— Waist belt. An additional device in the form of a belt, which, when fastened, covers the user's body in the area of the belt. The specific design of this part may vary. So, in relatively small backpacks, it is just a strap made of nylon or other similar material, and in large volumetric models, two wide and thick “petals” are provided that are adjacent to the user’s sides and are interconnected by a small strap with a clasp. Anyway, the main function of the waist belt is to redistribute the load: it allows you to transfer the load from the shoulders to the pelvic area, which is especially convenient when carrying heavy loads. In addition, such a device provides additional reliability of fixing the backpack on the body.

The material from which the main part of the bag in the backpack is made. Note that modern manufacturers use a large number of materials, and the variety of their names and characteristics may well be confusing. So, for example, both high-quality Cordura and low cost Nylon 600D with very modest characteristics are based on nylon ; one and the same material can be classified by one manufacturer as nylon, another as polyamide, etc. Therefore, in practice, if this issue is critical for you, you can do this: find the exact name of the material used in the backpack (for example, on the manufacturer’s website) and, based on this data, find out its characteristics (up to the reviews of real users).

A few general points for choosing a backpack, taking into account materials:

• The denser varieties of the same material are usually stronger, more reliable and less permeable, but weigh more and cost more. Therefore, it is worth considering what loads you will have to carry and in what conditions - it does not always make sense to pursue maximum thickness and strength.
• Water repellency is often a double-edged sword. The fact is that such materials get wet really badly - but they dry just as badly. And therefore, paradoxically, for long hikes in wet conditions, “wetted” fabrics may turn out to be more convenient: the contents, of course, will have to be carefully packed from dampness, but the back...pack itself will dry quickly during parking.
• UV resistance is useful in any case, but it is especially important when hiking in the mountains, where UV levels are by definition high. This is due not only to the appearance - low-quality material can even lose strength.
• When choosing a backpack for hunting (see "In direction"), it is advisable to pay attention not only to strength, water resistance, etc., but also to "noiselessness" - many varieties of synthetics make a noticeable noise during friction, which in no way contributes to the successful tracking of prey .

The material from which the bottom of the backpack is made. This parameter is in many ways similar to the material of the backpack itself, see "Material" for more details. Separately, it is worth noting that in this case, resistance to pollution and ease of cleaning can also be critical — after all, it is the bottom of the backpack that usually comes into contact with the ground.
