Since William Stanley invented the all-steel vacuum bottle in 1913, the Stanley brand has been a part of countless adventures and even more shared memories. From camping trips with dad to adventures with friends, our products are prized possessions passed down from generation to generation. All Stanley Vacuum bottles are built with rustproof and naturally BPA-free 18/8 grade stainless steel that takes a beating, a durable hammertone powder coat, a wide mouth for easy cleaning and ice compatibility, as well as our Built for Life lifetime warranty.
