About Klean Kanteen
Klean Kanteen began in 2004 with a simple idea: create a safe, reusable alternative to single-use plastic bottles. The first stainless-steel, BPA-free bottle was designed in Chico, California, and soon after the Cresswell family took the lead, expanding the mission and product line. From insulated tumblers to lunch boxes and straws, every Klean Kanteen product is built to last, with eco-friendly innovations like Climate Lock® vacuum insulation and the chip-resistant Klean Coat® finish.
As a Certified B Corp and member of 1% for the Planet, Klean Kanteen has donated millions to environmental nonprofits and remains committed to a healthier planet, one reusable product at a time.

What are people saying about the Reusable Stainless Steel Bamboo Cap – Leakproof?
This was what we were looking for. We needed to be free of plastics and all things microplastic! We did our research and not only are the bottles easy for kids to hold the caps are easy to unscrew! Would buy again!
Just as described. Love that this replacement cap has no plastic!
Very sturdy and high quality.
You should offer this instead of plastic for ALL bottles, as an alternative and at no extra cost - for the growing number of people who avoid plastic, particularly black. I resent buying a premium product and then paying so much for a replacement cap to make it right.
Looks and works great!
How to use
Using this bamboo cap is simple. Just twist it securely onto any compatible narrow-mouth stainless steel bottle to create a leakproof seal. The cap’s stainless steel interior ensures that beverages never touch plastic, while the sustainably harvested bamboo top adds a natural, stylish finish. Use the built-in loop to easily attach your bottle to a bag or carry it on the go. To maintain its quality, handwash the cap and avoid using it with hot liquids. With proper care, it will keep your drinks secure and your lifestyle eco-friendly for years to come.
