How It Works
Turn plain water into a functional drink that moves with you
Each TOAK cap holds a powerful mix of fresh ingredients activated the moment you twist.

Step 1
Add Water
Fill your TOAK reusable bottle with water, leaving about an inch of headspace for the ingredients to mix.

Step 2
Pick Your Flavor
Attach your cap of choice to the bottle and get ready for instant refreshment!

Step 3
Twist to Activate
Twist off the cap. This action releases the pressurized ingredientes from the chamber, into the water, instantly mixing them.
What is Vessl™?
Vessl™ is the patented technology inside every TOAK cap. It keeps active ingredients fresh using nitrogen and eliminates the need for preservatives. When you twist the cap, the chamber opens and releases the ingredients, instantly blending fresh flavors, vitamins, and functional ingredients into your water. No mess, no measuring, just a fresh drink whenever you want it.
Why Vessl™?
Over time, functional ingredients (such as antioxidants, vitamins, minerals, etc.) may:
• Settle,
• Separate
• Lose efficacy
• Lose flavor
• Fade in color
• Expire
Unlike any other teas, yerba mates, energy drinks, or flavor enhancers on the market, the pressurized Vessl™ technology protects ingredients without the need for preservatives or powders.
How Vessl™ Technology Works
It's in the cap!
- The Vessl™ cap has a chamber that is filled with ingredients and pressurized with nitrogen. This keeps the ingredients sealed and protected without the need for preservatives.
- Tighten the cap onto any TOAK® reusable bottle.
- When the cap is twisted off, the ingredients are propelled from the chamber and instantly mix with the water inside the bottle. No need to shake, simply twist & sip!
