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.

Love. I use it daily. No plastic is the best. Thank you.
J
I bought this to fit bottles in a smaller bike frame but the cap still sticks out more than I was hoping it would. It does make the bottles slightly shorter than with other caps.
C
Much more sturdy design than the cap that normally comes with the corresponding water bottle size.
T
Best caps! I like that there is NO PLASTIC!
I
Best lid for classic bottles ever. I’ve owned multiple plastic loop caps, sippy caps and sport caps for classic bottles. This is the only one that lasts many years of use and it is simple and beautiful. I only wish that I can buy more. Please continue to make this cap!
How to use
Using the Classic Steel Loop Cap is simple and reliable. Just twist it onto your compatible narrow-mouth stainless steel bottle to create a secure, leakproof seal. The all-stainless interior guarantees your drinks never touch plastic, while the sturdy loop makes it easy to attach your bottle to a bag or carry it by hand. It’s dishwasher safe for quick cleaning, though it’s not recommended for use with hot beverages. With its tough, minimalist design, this cap is built to last and keep your hydration routine eco-friendly.
