Frequently Asked Questions
Everything you need to know about our sustainable hydration solutions.
What materials are Klean Kanteen products made from?

Are your flasks and canisters dishwasher safe?

We offer a 30-day return policy for unused products in their original packaging. We want you to be completely satisfied with your purchase, so please contact our support team to initiate a return or exchange.
Does Klean Kanteen offer a warranty?
Yes, we stand behind our products with a Strong as Steel lifetime warranty. This covers manufacturer defects in materials and workmanship to ensure your investment in sustainability is protected.
Are the lids interchangeable between different bottle sizes?
Many of our caps are designed to be universal across specific lines. For example, all TKWide caps fit all TKWide bottles, and all Classic caps fit all Classic bottles, allowing you to customize your hydration experience.
