Backpacks are a type of bag that are designed to be worn on the back, supported by two straps that go over the shoulders. They come in a variety of sizes, styles, and materials, and are typically used for carrying items such as books, laptops, clothing, and other personal belongings.
Modern backpacks often have multiple compartments, including a main compartment for larger items, as well as smaller pockets for organizing smaller items. They can be made from materials such as canvas, nylon, leather, or polyester, and may have additional features such as padded straps for comfort, waterproofing, and specialized compartments for electronics.
Backpacks are popular among students, hikers, travelers, and commuters due to their versatility, durability, and convenience. They can be easily carried on the back, leaving the hands free for other tasks, and can distribute weight evenly across the body to reduce strain on the shoulders and back.
