A backpack is a versatile and convenient bag designed to be carried on one’s back using two shoulder straps. It is commonly used by students, travelers, hikers, and professionals to carry books, laptops, clothing, or other essentials. Backpacks come in various sizes, colors, and materials, often featuring multiple compartments and zippers for better organization. Some even include padded straps, water-resistant fabric, and ergonomic designs for added comfort and durability. Whether for daily use or adventurous journeys, a backpack is a practical companion that keeps your hands free while evenly distributing the load across your shoulders.
