This word was given to tourists by the Germans, giving it the name of a bag over their shoulders in which they carried weights. The backpack has many parts, shoulder straps, belts that can significantly facilitate the process of carrying various loads, making it more convenient. Many different compartments and pockets, located so that it is convenient for a person to reach them without taking off their backpack, create special comfort for the tourist and greatly facilitate travel. Choosing a backpack for a hike is a very important and serious procedure, which determines the mood of the upcoming trip: will the hike be a pleasure, or turn into a painful event with back pain and wounds on the skin. To avoid such an unpleasant outcome, both men and girls need, first of all, to base their choice of a backpack taking into account the anatomical features of their own body, because there are many options for this accessory - with frames of different types, large, medium or small sizes, with ties on the chest and hips , or without them. So, by design, they are divided into: soft - do not have a frame base; anatomical - semi-rigid backpacks (here rigid duralumin or plastic plates (inner frame) are located in the backpack "back", anatomically curved and suspended from the belt); easel - frame rigid (easel backpack has an aluminum or titanium frame, suspended on a fabric belt, this design allows you to distribute the weight of the load on the shoulder and lumbar zones, forming an air "cushion" between the back and the backpack, which does not allow the back to sweat).
