Comparison Osprey Celeste 29 29 L vs DAKINE 101 29L 15 29 L

— Universal. The term " unisex " is also used. These backpacks are suitable for most adults, regardless of gender.

— For women. Specific models created taking into account the differences between the female physique and the male one — first of all, this concerns the shape of the back and the location of additional ties (see "Design"). In addition, women's backpacks can have a distinctive design.

— For children. Children's backpacks by default are not designed to carry a large amount of weights, respectively, they have a small volume — usually less than 20 liters, with rare exceptions in the form of teenage models. In addition, various backpacks are designed for children of different ages and sizes, and can have an appropriate bright design. In models for this purpose (especially urban ones), reflective stripes are often provided, as well as a special pocket or patch for indicating the contact details of the parents.

— 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).

— 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.

- Sealed. This feature means that the backpack can be hermetically sealed, preventing water from getting inside (not to be confused with the included rain cover). In addition, such models are usually made of waterproof materials. Such properties can be indispensable in conditions of high humidity - for example, when rafting down a mountain river, when splashes constantly fall on things in the boat.

— Rolltop closing method. A special method of closing the backpack, allowing you to adjust its height and actual volume depending on the degree of fullness. The Rolltop backpack has the appearance of a bag with a soft upper part, which, when closed, rolls into a characteristic roll and is secured with a special fastener. This design, when closed, closes the backpack very tightly and reliably (almost hermetically), and when open it provides a wide neck, making it easier to access the contents of the bag; and there are much fewer fasteners in such backpacks than in traditional ones, which significantly simplifies use and reduces cost. At the same time, for a number of reasons, this design is considered suitable mainly for urban models; in other types of backpacks it is much less common.

— Top valve. Initially, the top flap is a piece of fabric that covers the top of a closed backpack and provides additional protection (mainly from ba...d weather). However, in modern backpacks this part is often equipped with its own pockets and actually represents an additional slot; in some models, such a slot is even removable and can be used as a separate handbag.

— Side opening. Possibility of access to the contents of the backpack through a clasp or flap on the side. This feature is especially relevant for roomy models that have a large height: you do not have to disassemble all the contents lying on top to get to the things at the bottom of the backpack.

— Bottom opening. The presence of a fastener at the bottom of the backpack, which provides access to its contents from below. The purpose of this function is similar to the side opening (see on top): to facilitate access to things located at the bottom of the backpack. It is especially useful for high-volume models, although it can also be useful for a relatively small product for urban or sports purposes. There is also a slightly different design option: the lower clasp opens not into the main slot, but into a small slot separated by a partition (the partition can be made opening, or even removable, which allows you to combine the lower slot with the main one).

— Front opening. Another additional way to access the contents of the backpack is through the clasp on its front side (opposite the back). Much the same as the side opening described on top, but the opening on the front can be made larger, making it easier to both access contents and load bulky items.

— Full opening. The possibility of full opening provides convenient access to the entire contents of the backpack. In practice, it is usually implemented using special designs of locks and zippers that run along the entire perimeter of the product. The backpack opens like a book, allowing you to quickly and easily access the items you need without removing all the contents. At the same time, this design solution makes it easier to organize the packing of things when packing them into a backpack.

— Output of the drinking system. Possibility of installing a sports drinking system in a backpack. This system consists of a soft synthetic container for water, with a capacity of up to several liters, and a tube with a valve. Accordingly, to install it, the backpack must have a slot for the container, a hole for the tube to exit, and a device for fixing it from the outside. The tube is usually secured to the backpack strap within easy reach; thanks to this, you can take a sip of water at any time without stopping or being distracted by opening/closing your backpack, which is especially useful on long hiking or cycling trips. The drinking system itself is usually not included in the package, but there are exceptions (see “Hydrator included”).

— Possibility of folding. The ability to compactly pack a backpack - for example, in a special case or tube. A useful feature if you need to travel with an empty backpack: transporting it packed in this case is often more convenient than carrying it on your shoulders without a load. The possibility of folding is found mainly in sports models (see “Purpose”).

— Change in volume. Possibility to increase/decrease the volume of the backpack. Most often, this function is provided by unfastening the zipper along the perimeter of the model itself (in fact, the volume of the main slot increases according to the principle, as is done in suitcases), there are exceptions with the location of the zipper at the bottom or front. Do not confuse changes in volume with screeds. In this case, changing the volume physically increases the size of the backpack by releasing hidden (folded or zipped) parts of the main or additional slot.

— Single-strap. Backpacks that have one strap and are designed to be worn over the shoulder. Single-strap products are found both among youth urban models and in specialized categories of backpacks, in particular tactical ones (see “In the direction”). This design not only provides the backpack with an original appearance, but also provides some very practical advantages. Thus, a single-strap backpack can be easily moved on the stomach - for example, to get something out of it, or for convenience in public transport. Also, such a product is more convenient when shooting with a rest on the shoulder than a classic backpack (of course, if you rest the weapon on a shoulder that is not covered by a strap). And for additional convenience, the design may include a side belt. On the other hand, single-strap backpacks do not distribute weight as evenly as classic backpacks and are not well suited for carrying heavy loads; therefore their volume is usually small.

— 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 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 backpack i...tself 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.

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.
