The Kanpai Bottle by Snow Peak is a double walled stainless steel thermos that works to cool, keep warm, and of course enjoying beverages on the go. Snow Peak made this Stainless steel bottle with three differnt lids- you'll be able to specialize to become a portable micro cooler, thermos, or drinking container. Place the cooling lid in the freezer for 12 hours, place your can of pop (or soda), in the Kanpai Bottle, and you'll find that this feature is made for keeping a 12 oz / 16 oz (500 ml model only) can cold, with only a 2 C degree drop over 6 hours. Double walled to insulated, using the insulated lid, it's engineered to keep beverages hot, or soup warm over 6 hours, only droping from 95 C (nearly boiling) to 60 C. And if you decide you'd like to drink this beverage, there's a lid for that too. Almost like that one fruity cell Pod thing. Amazing.
