Traditionally, a backpack is a cloth bag attached to a set of shoulder straps. Backpacks are used to carry items such as books, sports equipment, or camping supplies. They can also be worn as fashion accessories.
There are four main types of backpacks. They are frameless, internal frame, external frame, and bodypacks.
A frameless backpack, also known as a rucksack, is made of nylon or canvas. The main features of this type of backpack are a padded shoulder strap and a frame. These backpacks are ideal for hiking. They are often supported by a lightweight metal frame.
An internal frame backpack was first invented in 1967 by Greg Lowe. It has an aluminum frame, which helps to distribute weight evenly. However, these backpacks often have a smaller load capacity than external frame backpacks. They also are not as comfortable to use when walking.
A frameless backpack, also known a daypack, is smaller than an internal frame backpack. These backpacks may be padded or unpadded. They may also have an extending handle on the bottom. They are most often used on trains or airplanes.
An external frame backpack is typically made from a lightweight metal alloy or reinforced synthetic polymers. These backpacks are designed to be lashed to a metal or plastic carrying frame. They are not as comfortable to wear as an internal frame backpack because they have a smaller fabric “sack” portion.
These backpacks are typically designed to allow for a larger storage compartment. However, they may not have lash points for heavier items.
