You don't have many possessions at your home that will work for 24 hours straight. It's time you added this water bottle to your hydration routine. It may look simple on the outside but there's some high-tech innovation going on inside, designed to keep your liquids cold for a full day and hot for up to 12 hours. The key is the triple-walled insulation interior, a design made from high quality, BPA-free stainless steel. Holding up to 17 ounces, the bottle is printed with a marble-inspired aesthetic, so it looks good on your desk.
