Key for each piece of equipment in the right place, according to the size of the backpack load.
Before placing on our shoulders a correct weight distribution is critical to carry loads high on a path, without suffering injury or exhaustion by excessive physical exertion. Of course, this is important in rucksacks of large capacity, of which we can distinguish three basic types.
40 to 60 litres: their most common use is for activities in which will at least spend a night out, and even a weekend (2-3 days), where it is already necessary to carry the sleeping bag, cover bivouac or a lightweight tent, supplies, heater…
60 to 80 litres: is used for activities of several days (3 to 6 days) or for logístics in mountain.
+ 80 litres: are the backpacks of the type expedition, for outputs of a week or more, models really big and heavy, where it is essential that (back, shoulder pads, hip belt) charging system is of very high quality to avoid injury to your users.
Arrange the load
There are many ways to do it, depending on the type of terrain chosen outdoor activity, climatic conditions, duration of the output or personal preferences. Computer graphics on the left shows a, which is not unique, because for all variants, there is a concept, an idea of base: get to the center of gravity of the load is closer to the back, centered both in height and in width. I.e. backpack should be stuck to the back and no more weight on one side than another, to not cause inertia to walking, especially on hilly, with many changes in level.
The load must also be fixed to it nor unbalanced us his movement, and for that we will use different compression straps. If this is not achieved, it seems that we carry more weight than we actually load, it will increase tension by making more uncomfortable step, greater effort and fatigue.
The general rule, normal logístics, or easy paths with low gradient and firm surface to land, is that greater weight should be as close to our axis, the more stuck possible on the back and on the top of the backpack (at the height of homoplatos and shoulders). But when we are going to progress through difficult terrain will load in the central or central-baja backpack, lower area but also more attached to his back which we can. The reason is that our torso is going to move more towards the sides, and if we load too high will us more, so we have a worse body balance-unbalance.
It is good to consider the different parts that usually have all the backpacks high capacity to make easier the process of filling them with our team:
Upper compartment: close the main entrance of the backpack and can have several divisions. It is the area perfect for storing small, relatively light elements, and that are required to have on hand, such as: map, compass, flashlight led, goggles, sunscreen, Kit first aid, Swiss army knife, initiator of fire, etc. Do not place heavy or bulky objects because they destabilize much or they can hit us head. The second part is the central body, which is the area of more volume, and which means to follow a certain order in your filling. The lighter elements, such as clothing, must occupy the lower, upper and lateral parts. And the heaviest should be in the center closest to the body.
These heavy elements can be, for example: kitchen equipment (heater pans, canned provisions, batteries and Chargers for electronic, carp, etc.). If the backpack hydration bag compartment, it is on this central body and glued to the back. Finally, the bottom compartment. Most of more than 40 liters backpacks have a lower pocket, with its own access zip. This area is ideal for elements of low weight and bulky, which would occupy too in the central compartment, such as the sleeping bag, or sneakers or hiking boots extra. In terms of the exterior pockets covered and network, are designed for small items, for example: bottles or thermos with liquid, food running, cameras, and other equipment. As we said, it is important to maintain about the same weight of load on both sides of the backpack. Finally, as a general rule, the backpack 25% of the weight not must load more than during a route of long distance in average conditions.
Summer is the time of the long holiday, in which we can use this large backpack for holiday (http://www.newvilleoutdoor.com/index.php/2016/12/backpack-for-holidays/), with included nature camps.
