Cirkul Stainless Steel Bottle

You insert a flavor cartridge into the top of the bottle lid and twist the dial to adjust the flavor intensity. The system mixes the concentrated flavor with plain water as you drink, allowing you to control exactly how strong or subtle you want your beverage to be.

Yes, you can use the bottle for plain water. However, the system is designed to function best with a cartridge inserted, so you will need to keep one in the lid or use a blank cartridge to ensure the seal remains secure.

The vacuum-insulated stainless steel construction is designed to keep beverages ice-cold for up to 24 hours. Performance can vary slightly based on the ambient temperature and how often the bottle is opened.

The stainless steel bottle itself is generally durable, but hand washing is recommended to preserve the integrity of the vacuum insulation and the finish. The lid should always be hand washed to protect the internal flavor-mixing mechanism.

No, the flavor cartridges are formulated without added sugar or artificial colors. This allows you to enjoy a variety of taste profiles without the extra additives found in many traditional flavored drinks.

This starter kit includes a 32-ounce bottle, which is a standard size for daily hydration needs. It provides enough capacity to get you through a commute, a workout, or a long afternoon at the office without constant refilling.
