rucksack

A rucksack is a type of bag designed for carrying items on one's back, typically featuring two shoulder straps. It is commonly used by hikers, travelers, and students due to its ability to distribute weight evenly across the shoulders and back, making it suitable for carrying heavy loads over long distances. The term 'rucksack' is more prevalent in British English, while 'backpack' is more commonly used in American English.
