A backpack is a versatile and essential item used for carrying personal belongings, especially while traveling, hiking, or commuting. Typically made from durable materials like nylon, polyester, or canvas, it features two shoulder straps that allow it to be worn comfortably on the back, distributing weight evenly. Most backpacks have multiple compartments and pockets to help organize items such as books, laptops, clothes, water bottles, and accessories. Whether used by students, travelers, or professionals, a backpack offers convenience, mobility, and style, making it a practical choice for daily use.
