A beautiful small bottle for daily life and adventures. It needs no introductions, so let's jump to the features.
OK, it's aluminum. Do you get Alzheimer's, autism, and astigmatism from it? The short answer is no, but for added security, the inside has a multi-layer EcoCare coating to completely separate your drink from the metal. It's safe for the purpose and durable as well. For example, it won't crack if you dent the bottle.
The bottle is sealed and leakproof even when upside down, and it's rated for carbonized drinks, acidic juices, milk... If you are willing to pour it down your throat, this bottle can handle it as well. Tastes and odors won't stick to the bottle: just wash it after using, and it'll be as neutral as a minister's speech.
