🎒 A rucksack is a type of bag designed to be worn on the back, typically made of durable material such as canvas or nylon. It usually features shoulder straps and often includes additional compartments and pockets for organizing belongings. Rucksacks are commonly used for outdoor activities like hiking, camping, and backpacking, as well as for everyday use when carrying books, laptops, or other essentials. They provide a convenient and hands-free way to transport items while distributing the weight evenly across the wearer's back.
