This large capacity rucksack was used by the donor, Leonard V. B. Sutton, of the 87th Mountain Infantry Regiment while at Camp Hale, Colorado in 1942. He did not specify if he used it past that time, or if he was deployed overseas to Italy. These rucksacks were developed for the mountain soldiers and absolutely necessary to carry the huge loads needed to survive the cold, this unique pack put the load on a man's hips instead of his shoulders. The Quartermaster Catalog advised that the pack's tubular frame could be removed and made into an emergency sled.
