Alternative names include haversack from the German "Hafersack" meaning "oat sack" (which more properly describes a small cloth bag on a strap worn over one shoulder and originally referred to the bag of oats carried as horse fodder), "Kraxe" (a German rucksack with a rigid framework), and "bergen" (a large load-carrying rucksack, from a design issued by the British Army during the Second World War). In fact, Britons used to call Alpine-style backpacks "Bergen rucksacks", maybe from the name of their creator, Norwegian Ole F. Bergan, combined with the name of the Norwegian city of Bergen.
