Even the best backpack isn’t effective and causes back pain if not adjusted properly or if it has not been prepared optimally. For a trek to success it is important to adjust the height of the body. By allocating the optimum weight walking better and increases balance.
How to set your backpack optimally?
- To try the backpack you should upload it (ca. 8 kg) and then to loosen all straps. Wear the backpack.
- Place the lap belt one half of the hip (place to stick out the bones) and tighten. Extreme parts of the pad should protrude approximately 3cm from the sides.
- Tighten the shoulder straps so the main weight is still divided on the lap belt. The shoulder padding should be in contact with the body. The adjustment straps at the end of the shoulder straps should be up to the armpits. If they are too high means that the height of the dorsal fin is too low (the shoulder straps are too tight or drift away). If they are too low means that the spine is too long (irritation on neck and arms).
- Close and tighten the chest strap until you get a comfortable position without compromising breathing. The chest strap stabilizes the shoulder straps and distribute the weight properly.
- Adjustment straps: Depending on the terrain, the adjustment straps allow to increase freedom of movement (loosen in case of land) or improve load distribution (in case of difficult terrain). In order to ensure an optimal function, the adjustment straps have an angle of 45° (30° to 60° max.).
How to load a backpack?
At the bottom are especially made lightweight objects like e.g. sleeping bag and toilet bag. The cracks can be filled with t-shirts or underwear. Read travelling tips on http://www.sciencedict.com/tips-for-traveling-with-backpack-rucksack_201605/.
Main compartment (middle part)
The main compartment are put heavier items e.g. ropes, carbine, shoes, drinks, clothes and food.
Side entry pockets you can place the curtain rods or bottles.
Compartment in the hood
Here are placed small objects that must be on hand such as camera, tissues and the first-aid set.
Compression straps allow you to adjust the volume to your content as needed (e.g. as the pantry decreases during 2-day excursions). Clutching ribs improve the allocation and weight control.
We recommend that you attach only lightweight objects to your backpack, as mat or wet clothing. A elastic draw string can serve to secure the trekking poles.
If you expect clouds it is advisable to put clothes, sleeping bag etc in waterproof bags or plastic.
The ideal weight distribution favours the walk
It is important that the backpack is prepared in a balanced way. Depending on the terrain the center of gravity of the backpack must be higher (simple) or lower (hindering terrain).
The CG is placed at the bottom of your backpack and then away from the Centre of gravity of the body. This displaces the weight down and the body is constantly fighting weight of the backpack. The shoulder straps and then the shoulders are more stressed. Difficult terrain requiring a nice balance this can result in a high risk.
Simple terrain – eg. Woods and trails
On easy terrain with a good surface (e.g.-Alpine paths) the center of gravity of the backpack should be at the shoulder blades.
Difficult terrain-trails in the mountains and Alpine
In order to move the center of gravity of the backpack to the body, it is necessary to place heavy items on the bottom of the main compartment. Adopting a slightly tilted forward you balance the weight and do best to remain in balance.
