What We Love


  • "Grows with child, universal tops, well made product! Our favorite cups, hands down. Trying to avoid plastic at all costs and these are wonderful. They hold a generous amount for my constantly thirsty child, she’s 1 1/2 and can even carry it when it’s full of liquid.” - Sydney S. , Aug 10 2019
  • “Best stainless steel/plastic free bottle on the market! Such a great water bottle! Doesn't leak (ever!). And I love that it contains no plastic. It's very easy to clean, other stainless steel water bottles have plastic lids with spouts that you can't fully clean. I love this so much!" -Amazon Reviewer, May 4 2016
