A refreshing sip in the schoolyard or on the go? With the flip-up insulated bottle, your little one's drink stays cool for up to twelve hours, and warm drinks remain pleasantly warm for up to four hours. The handy flip-up system makes drinking extra easy, even for small hands. The bottle is double-walled, leak-proof, and has a straw connected to the spout. Also suitable for carbonated drinks, although we recommend removing the straw and not filling the bottle completely. Thanks to the carrying loop, you can take the bottle anywhere. The cap is dishwasher safe, but it's best to wash the bottle by hand.
