KOR Aura bottle available in 6 colors. Style and performance meet in a tapered profile, an ergonomic handle integrated into the lid and the threadless Perfect Spout for comfortable drinking. Kor's COBALT bottle also serves as a natural optical filter to absorb external light and preserve and prolong the state of water, particularly enhanced water such as alkaline, structured or super-oxygenated. KOR believes in sustainable hydration: the concept that not only is hydration important to your health but how you hydrate is important as well. Not only for your health but for the health of the world. KOR vessels are designed to be functional and attractive with the belief that a well designed, beautiful product will be used longer, lowering landfill waste over time.
