A backpack is a versatile and convenient bag designed to be carried on a person’s back, typically supported by two shoulder straps. It is commonly used by students, hikers, travelers, and commuters to carry books, clothing, gadgets, or other essentials. Most backpacks have multiple compartments and pockets, making it easy to organize items efficiently. They come in various sizes, styles, and materials, ranging from simple fabric bags to high-end waterproof and padded versions. Backpacks are appreciated for their practicality, allowing the user to keep their hands free while evenly distributing weight across the shoulders and back.
