The Built Hydration collection combines style and functionality for a result that is perfect for the busy, health-conscious lifestyle. This Pureflow Apex tumbler is an advanced innovation in drinking technology with its insulated design and unique 360 lid. A double walled, vacuum-insulated body is made of 18/8 stainless steel which insulates cold drinks for up to 24 hours and hot for up to 8 hours, keeping them as fresh as any just-purchased option. The double wall also means the exterior will stay a comfortable temperature to hold. The lid is leak-proof and provides 360 drinking for the ultimate experience in convenient drinking on the go. A simple turn anti-clockwise will open the lid for secure drinking from any angle. Continue turning to fully release the lid for easy cleaning: the tumbler is hand wash only, while the lid is dishwasher safe. A striking design, this model is visually impressive as well as functional with a sleek shape, deep teal finish and the Built logo etched in silver. This tumbler fits standard sized cup holders to sit comfortably on car journeys. BPA free. Capacity: 470ml/16fl oz.
