A backpack is a type of bag or purse that is carried on the back. For this it has two straps that go over the shoulders.
Backpacks can be used to transport all types of objects. They are very popular on trips and excursions , but they are also used in school and even in everyday life.
Given this variety of uses, there are multiple types of backpacks. The largest are those used in expeditions and include a space for storing bottles, among other divisions. Among the smallest are children's backpacks , intended for young children.
Backpacks generally have several compartments and pockets. Thus the user can choose where to store everything and organize their belongings according to their comfort .
On the other hand, it is important that backpacks are resistant: otherwise, they can break due to the weight of the load . Typically, they are manufactured with polyamides and have different closures and snaps to secure their contents.
It should be noted that many backpacks have small wheels integrated. This way, the person can put the bag on their shoulders or drag it across the floor.
Suppose a young man plans to walk several kilometers along the beach. The boy takes his backpack and puts a coat in it in case the temperature drops; a bottle of water; a packet of cookies; a wallet with money ; and the house keys. This way you can enjoy the ride with your hands free and have various elements at your disposal that may be useful to you.
Similarly, when going camping it is practically impossible to ignore the backpack, although in this case models designed specifically for this type of experience are used. This is the so-called mountain backpack , although it is also known as a sea or hiking backpack . The characteristic that distinguishes it from the others in the first place is its capacity: it must exceed 40 liters. Its materials must be especially resistant, both to cope with the weight of its contents and to not deteriorate easily in the face of inclement weather.
In the body of a mountain backpack there are two separate parts although connected by a closure: a small one, located at the base, where the sleeping bag is stored, and another large one, intended for the rest of the objects. On its sides it is common to have various pockets for things that the user may need more frequently, such as drinks, money and keys.
The lid of the backpack is known as the headboard or mushroom , and it is also common for it to have one or two pockets, both on the top and bottom. In them you can leave items such as a scarf, hat, sunglasses.
Finally there is the trellis , which is considered the fundamental part. It is covered in foam to protect the back from the rigid structures that act as support for the backpack, two vertical bands or handles designed to stabilize it and stick it to the body and a belt to hold it and improve weight distribution. Some mountain backpacks include solar panels , ideal for charging electronic devices.
It is important not to confuse them with sports backpacks , although both types are used in physical activities . These are smaller, less rigid and have fewer compartments, since they are intended for the transport of a few materials, which are used in sessions whose duration is counted in minutes or hours, but not to be away from home for days. They are marketed in generic versions, for any sport, or specific ones.
