Stanley’s Master Series Bottle Keeps Coffee Hot for 40 Hours

Whether you work in the trades, spend time in the wilderness or just like having good coffee at your fingertips on the go, you’re familiar with Stanley insulated bottles and thermoses. Stanley is outdoing even themselves with the new Master Series Bottles that can keep coffee hot for up to 40 hours. The top of the line Master Vacuum Bottle is the largest of the bunch and has 1.4 quarts of space for coffee, tea or even iced beverages. The QuadVac insulation lets this bottle keep drinks hot for 40 hours, cold for 35 hours or iced for 160 hours, so you’re never going to have to worry about your drink coming out the wrong temperature. If you don’t need quite as much capacity, there are also 18oz and 25oz varieties made with the same durable construction and QuadVac insulation that are rated for hot beverages for 12 hours or 27 hours, respectively. It might be time to upgrade that tried-and-true green Stanley thermos you’ve been using for years.
