Working...

How does the system work?

Using the system is incredibly easy:

1 - Remove the Stage cartridge from package

2 - Shake the cartridge well

3 - Thread onto the Cirkul cap

4 - Fill bottle with water and thread on the cap

5 - Use the dial to adjust the flavor and electrolyte consumption

6 - Enjoy and make sure to recycle when done!

TIPS FOR BEST PERFORMANCE - Shaking the cartridge in between fill ups helps our electrolyte packed formula flow best. Also make sure that the small silicone valve under the cap has a fully cut "X" in it, high quality silicone has a knack for healing itself!
