Every new parent wants to make sure their baby’s environment is as healthy as possible. Klean Kanteen can help with that. We designed a special adapter that works with Avent’s™ patented sippy cup spout so you can put your energy into the important stuff like bedtime stories and teaching junior to say “mama” and “dahdah”, not worrying about whether your child’s bottle is leaching chemicals.

Just like every other Klean Kanteen, our 12oz bottle is made from 100% recyclable, high-quality, food-grade stainless steel so it doesn’t need a special lining like some other metal bottles. It’s completely BPA-free and won’t leach chemicals, toxins, or funky flavors into your baby’s water or juice.

It’s designed for small hands, making it easy to hold. And the large-mouth makes it easy to clean too—just scrub it out with soap and water, or toss it in the dishwasher.

Holds 12 fluid ounces, weighs 4 ounces, opening diameter 1.75”, which accommodates large ice-cubes!
