1913, William Stanley invented the all-stainless steel vacuum bottle. Since then, it has been passed down from generation to generation, becoming so synonymous with stainless steel water bottles in America that people say "Stanley." It is said to be so durable that it can withstand being dropped from 4000 feet or run over by a tractor. Even after more than 100 years, Stanley water bottles continue to evolve, creating "water bottles for life." Camping cook set.
