How to Choose a Backpack?

CHOOSE YOUR BACKPACK

Choosing a backpack requires attention. The ideal backpack is the one that best suits your physical structure and the activity to be developed. Knowing how to adjust it and how to arm it according to our activity will increase the harmony of relationship with the team and will allow better enjoyment of the benefits of this.
The variety of models, colors, sizes and prices can be confusing.
Pay attention to the following items:
SIZE
COST X BENEFIT
ERGONOMICS
EXTERNAL VOLUME
SIZE
The size of a backpack is determined by its capacity in liters. That may sound pretty abstract to anyone who is unfamiliar with the subject and may not mean anything to anyone who is going to look for their first backpack. Small ones generally have a capacity ranging from 20 to 40 liters. The average capacity ranges from 45 to 60 liters and large or cargo can contain from 60 to 90 liters. Think first what activity you are going to develop with that backpack. There are space backpacks for cycling, mountaineering, or hiking. If a multifunctional backpack is needed, it is advisable to choose a stocking with good resources to adjust. Keep the load firm even when the backpack is not fully charged. It is also important to have the option to attach insulators and other accessories to the external structure of the backpack.
Keep in mind that filling it up could compromise the durability of it.
COST X BENEFIT
More resistant materials and better quality finishes can cost a little more to buy, but they tend to last much longer. Currently the backpacks have been developed and present a series of special solutions for each activity. That is why it is not advisable to compare the price of the small with the large. If you are already practicing activities such as mountaineering, hiking and cycling for some time, keep in mind that the backpack is a fundamental item.
Invest a little more to have the best that the market offers the best, can mean years of tranquility.
ERGONOMICS
This concept refers to the possibility of fitting objects to the human anatomy. In the case of the backpack is essential. Providing cargo transportation in harmony with the human physical constitution is the main function of the backpack. When choosing your backpack pay close attention on how it fits your torso and hip. In women, it is necessary to verify that the curvature of the belts does not affect the position of the breasts, the use of inadequate belts can cause injuries in them.

EXTERNAL VOLUME
Side and back pockets are interesting for separating luggage and keeping certain items always at hand. Meanwhile, external pockets can be easily hooked in places of closed forest or obstruct locomotion in places of great movement such as terminals and airports. Ideally, the backpack should be narrower than the shoulders, lower than the head and have an unapproved profile without a back pocket. The models with detachable pockets, which can be used as small attack packs are very interesting.
ADJUSTING THE BACKPACK
The modern backpacks have several regulations and it is fundamental to know their functions to be able to adapt them to each situation. Knowing the details of your backpack and knowing how to regulate it well can be the salvation of an outing or trip. With the exception of back regulation, the others must be adjusted every time the backpack is loaded as these depend on the load, terrain, clothing and even the mood of the person who loads it. The more technical the activity the more stability is required to the backpack and tighter the regulations should be.
DORSAL ADJUSTMENT THE HEIGHT
The dorsal or height adjustment is usually the only fixed regulation of the backpack, that is, it is adjusted the first time according to the size of the trunk. Make this regulation very carefully and with the help of someone else. If done wrong this adjustment could overload the shoulders.

SIDE COMPRESSION TAPES
This type of adjustment is especially important for half-load backpacks, as it allows the load to be compacted closer to the back. Ideally, the backpack should be flat and rigid. The most common system is two or three horizontal straps on both sides of the backpack. The regulation is made by nylon buckles of the “just pull” type. It is good that you have at least fifteen inches of tape to put accessories. In this case bolts type male-female facilitate even more the operation.

RIÑONERA
This is the most important accessory of the medium or large backpack. Apart from the buckle that opens, closes and adjusts must carry another one that fix that regulation. At least one side must have free regulation that can be adjusted without opening the backpack. Pay attention that you adjust even if you lose weight or are shirtless. You can lose up to five pounds on a fifteen-day trekking out on rough terrain or at altitude.
Do not forget that the main function of the belt is to transfer the weight of the rucksack to the hip. Very soft bouncers of an apparent comfort are usually a martyrdom with the backpack loaded besides lasting much less. Many small backpacks have belt loops which do not transfer the load to the waist. They work as stabilizers and are very useful when climbing, running or walking on rough terrain. Finally you have to look at the quality of the clips because if they are plastic they will not last long, the good ones are of nylon and in spite of being similar you can see the sonorous “clack” they make when closing them.

MAIN STRAPS
As with the belt, the belts must be structured (semi-rigid) for greater efficiency and durability. The very soft belts end up deforming and decreasing the contact surface. The adjustment of the straps can be from top to bottom when the snaps are at the end of the strap and vice versa if they are attached to the base of the backpack.

SIDE STABILIZER
The lateral stabilizer is the item responsible for the stability of lateral movement of the backpack on the trunk. It must be adjusted after the belt washer and the main belts have been tightened, as their setting varies in each situation.

TOP STABILIZER
The upper stabilizer keeps the backpack close to the back and dislocates the weight to the front, which increases the efficiency of the waistband. Many backpacks allow you to adjust the height from these straps, which should be done after adjusting the back regulations. Ideally, the backpack should be kept a few inches above the shoulders.

PECTORAL STABILIZER
It is an excellent solution for heavy loads, rough terrain and long walks. It prevents the straps from entering under the arms and allows to transfer the “pull of the backpack” (tendency of the backpack to fall backwards) to the chest area, relieving the shoulders. Changing the regulation of the chest stabilizer throughout the day or even releasing it sometimes quite alleviate the discomfort of the upper part of the trunk.
