Back when our firstborn was using a sippy cup, his was the only Klean Kanteen in his playgroup. But now that our secondborn has reached sippy-cup age, we're finding it hard to keep track of ours in the melee. Something like this dangerously adorable bottle cozy could be the solution.
Handknit of acrylic yarn, these bottle buddies are machine washable and dryable. Each one is 6.5 inches tall and 2.5 inches across, and is stretchy enough to accommodate baby bottles and most water bottles. Available in gray and dusty blue.
