Introducing Oztent’s exciting new range of the Alpine Insulated Bottles. This stylish range has been developed using simple Oztent philosophies; they are tough, they are easy to use, and they are practical.The narrow mouth design on the bottles makes the bottles simple and hassle free to use while on the move which also helps eliminating spillage. These bottles are constructed with a double walled food grade 18/8 stainless steel and are vacuum insulated which keeps liquids cold up to 24 hours (even longer if you add ice) or hot liquid up to 12 hours. These bottles are also BPA free so you can enjoy the pure natural taste of water.
