A backpack is a versatile and essential bag designed to be carried on a person’s back, supported by two shoulder straps. It typically features multiple compartments and pockets, making it ideal for organizing and transporting books, clothes, electronics, and other personal items. Whether used by students, travelers, hikers, or professionals, backpacks offer a hands-free and comfortable way to carry belongings, evenly distributing weight across the shoulders. Made from durable materials like nylon, polyester, or leather, they come in various sizes, colors, and designs to suit different needs and styles.
