This half gallon 64oz vacuum insulated water bottle utilizes the innovative ThermoArmour technology to keep beverages cold for up to 48 hours and hot for up to 24 hours. It also comes with two lids - a straw lid and a spout lid. The bottle is made of high-quality materials, including 100% non-toxic BPA-free plastics and durable food-grade 18/8 stainless steel, which ensures protection against oxidation and flavor transfer. The BUZIO water bottle features a user-friendly design, thanks to the BUZIO powder-coat technology and wide mouth opening (2.2 inches). This makes it easy to hold, clean, and fill with ice. In addition to the water bottle, you will also receive a carrying pouch, two straws, a straw brush, a straw lid, a spout lid, and our worry-free lifetime warranty. We pride ourselves on providing friendly customer service.
