The Xtreme Canteen is a double wall, vacuum insulated, 18/8 stainless steel bottle. You can put any liquid inside of it. We like to say, “If you can think it, you can drink it.” The canteens keep your drinks icy cold up to 24 hours, and hot liquids hot for up to 12 hours. Whether it is cold or hot, your canteen will keep your liquid at the perfect temperature, with no condensation! Our canteens are BPA free, 100% recyclable and have a lifetime warranty. Xtreme Canteen’s goal is to educate consumers about the harmful aspects of single use plastic. This type of plastic contains harmful chemicals, which seep into your liquids, negatively impacting your health. In addition, single use plastic does not biodegrade, meaning it pollutes our planet forever. By choosing Xtreme Canteen, you are improving your bodily health and the health of our planet! (less)
