HOT ! Dark Green, Black, Gold

The KOIY Optima drinking bottle features a balanced aesthetic that is understated yet classy, with a unique and convincing presence. An outstanding masterpiece: elegant, versatile and flawlessly engineered. The Optima’s gold elements are plated with real 24-carat gold.

Its unique lid features a swappable ring and is made from a single block of stainless steel. Engraved meticulously with 1,500 micro-pyramids and mirror-polished by hand. 

The mouthpiece is laser-polished and shows no outward-facing thread. A unique drinking experience, topped off by a distinguished appearance. 

The body of the Optima is made of high-grade stainless steel and single-walled to maximize volume. With a volume of 970 ml / 32 oz., it adds real value to your hydration. Its leak-proof gasket makes it suitable for carbonated drinks.

Despite being made of stainless steel, the bottle is lightweight.  

Each bottle is assembled and tested by hand in Germany. Packaged by hand and shipped in our exclusive KOIY gift box.
