The KOR Aura, like all KOR drinking vessels, starts and ends with the drinking experience. With the Aura, KOR provides simplification and ingenuity at a value price for a re-usable bottle. Made from BPA-free Eastman Tritan copolyester, the health-safe KOR Aura is durable and beautifully clear. Each vessel features the KOR Perfect Spout design, a rounded lip spout that feels great on your lips and is large enough for chugging and ice cubes but small enough to minimize splashing. The Aura"s inviting twist-off cap shields the mouthpiece from germs and dirt. And its tapered body and ergonomic handle make it a joy to hold from any angle. Finally, as with all KOR hydration vessels, one percent of all KOR Aura sales go toward the support of important water initiatives through KOR"s "Thirst for Giving" program. Simplicity, ingenuity, sustainability -- the KOR Aura.
