Care and Use

Your Klean Kanteen® is made from thick, 18/8 (#304) stainless steel and is designed to be lightweight yet extremely durable. If you take care of it, it may very well last your lifetime. Check out our Care and Use page for a few tips to help keep your bottle fresh and clean.


We are proud of the materials and workmanship that goes into each Klean Kanteen, and we stand behind all of our products and accessories. But we also know that on occasion, things go wrong. Check out our Warranty page to submit an online warranty claim form.
