Klean Kanteen Classic Water Bottle

No, this is a single-wall stainless steel bottle. It is designed to be lightweight and portable, so it will not maintain the temperature of your beverage for extended periods like an insulated vacuum-sealed bottle would.

Yes, the Flip Seal Sport Cap is designed to be versatile. You can use it with the straw for upright sipping or remove the straw to drink directly from the spout.

Yes, the cap is engineered to be 100% leakproof when properly closed. This makes it a reliable choice for tossing into a gym bag or backpack without worrying about spills.

No, the interior is electropolished, which is a safe, non-toxic process that prevents the steel from retaining or imparting flavors. Your water will taste clean regardless of what you drank previously.

The bottle features a wide opening and rounded corners, making it easy to hand wash with a bottle brush. The stainless steel straw can be cleaned with a small straw brush, and all components are designed for straightforward maintenance.

The 18 oz Classic features a slim, narrow profile specifically designed to fit most standard vehicle cupholders and bicycle bottle cages.
