A backpack is a bag worn on the back that typically has shoulder straps to secure it. It can be frameless, or have an external and internal frame.
A backpack is commonly used for hiking, sports and school activities. It can also be used as a carry-on bag for airplane travel.
The word “backpack” is derived from the German phrase der rucken, which means “the back.” A rucksack, on the other hand, is a large backpack. It includes pockets and belts that allow it to hold a larger amount of gear than a backpack. It can be made of waxed canvas or technical materials and often features hip belts and chest straps.
There are many different types of backpacks available for every trip, adventure, and lifestyle. For example, one is specially designed for professional cooks and culinary students. It has a compartment for knives, cooking tools, and other miscellaneous equipment. Another is a heavy-duty, rugged backpack that was used by soldiers during World War II.
Backpacks are often used by hikers, runners and cyclists to carry heavy loads and other gear. They can have an external frame, or be frameless like a duffel bag. They may also be referred to as a knapsack, pack, sackpack, bookbag or satchel, depending on the context.
A backpack can be used to carry all the gear you need for a weeklong adventure in Europe, or just a few essentials for a short weekend getaway. A good backpack will keep everything organized and protected from pickpockets, while being comfortable to carry.
