A backpack is a versatile and essential bag designed for carrying items on your back, supported by two shoulder straps. Commonly used by students, travelers, and hikers, it provides a convenient way to transport books, laptops, clothes, and other essentials while keeping your hands free. Made from durable materials like canvas, nylon, or leather, backpacks often feature multiple compartments and pockets for better organization and easy access. Whether for school, work, or adventure, a backpack is a practical and reliable companion for daily life.
