110 years ago William Stanley Jr. invented the all-steel vacuum bottle. We’re celebrating this landmark anniversary in style with our new Milestones Thermal Bottles collection. We’ve dug into the archives to take inspiration from the most iconic and timeless bottles of the 1920s, 40s & 60s, combining them with our best insulation invention yet - 4D Thermology™. The 4D Thermology™ insulation gives your drinks 4 layers of hot/cold protection while out on all your outdoor or urban adventures. Keeping 1L of your beverages hot for 35 hours, cold for 37 hours or iced for 5 days without spilling a single drop. There’s also a double-wall full steel cup and a cork top steel-lined stopper to preserve the flavor integrity of your coffee or tea. Throw into the dishwasher once home, ready to hit the next day's hiking, fishing, commuting adventure. Available in 3 colors: 1920 Black Patina, 1940 Garnet Gloss and 1960 Vintage Green.
