Choosing a cap for your Klean Kanteen is all about your style and lifestyle. Are you an on-the-go bike commuter? Do you want something with no frills, just simple, sleek, and low-profile? Are you racing from school to soccer practice, then off to the co-op to grab fresh veggies for dinner? Do you need to clip your Klean Kanteen onto your backpack for a trail run or weekend trek?

Whatever you're looking for, however you need your cap to perform, we've got the right one for you. And all our caps are interchangeable between bottle sizes, so it’s easy to change them out depending on what you're up to. Klean Kanteen caps and spouts are made with BPA-free polypropylene #5.
