This Hydration tumbler is designed to make staying hydrated and maintaining a healthy lifestyle wherever you go even more appealing, while also reducing your plastic footprint with its reusable design. 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 6 hours, keeping them as fresh as any ‘just-purchased’ option. The double wall also means the exterior will stay a comfortable temperature to hold, while a sturdy Tritan lid easily slides open and closed for one-handed drinking. A sophisticated design, this model is visually impressive as well as functional with a sleek shape, matte black finish and the Built logo etched in silver. Perfect for taking smoothies, herbal teas or any hot or cold refreshment, this tumbler is ideal for taking with you for a nourishing boost in the car, on the commute or anywhere on the go. The bottle is suitable for a standard size cup holder and is BPA free for peace of mind. Capacity: 565ml/20fl oz.
