MiiR's got just the thing to keep your beverages perfectly cold...or perfectly hot. Their heavy duty Growler has got room for 64oz's of your favorite beverage and double wall vacuum insulation keeps the liquid cold for a 24 hours or hot for 12. They've also given the cap a threadless design to keep things clean and leakproof. MiiR recently launched funding for the Growler and is close to hitting its goal and have plans in place to ship the bottles in February 2014. Even better is that with each bottle purchased MiiR gives back and provides one person with clean drinking water.
