Klean Kanteen Sippy Cups (12 oz)Product Rating: Product Review (submitted on January 3, 2011):
We have a Kleen Kanteen Sippy for my toddler. The greatest thing about these is that I could fit the Avent tops to it. That made it an easy switch for her.
They are heavy, though, and I wouldn't use in a stroller without a tether for this reason. Also I would like to see them in a smaller/shorter size for little hands! I think that would be perfection.
A note from the bynature.ca team: Our Toy Straps work well to attach the Klean Kanteen to a stroller - http://www.bynature.ca/pippalily-toy-strap.html
