16oz. StrawSip™ Flaske med klaffelokk

My kid actually drinks more water now because she can sip without tipping the bottle back. The straw cartridge stays covered when it's clipped to her backpack, so I'm not worried about it getting gross between outings.

No more tipped cups in the car — my son just sips straight from the straw instead of tilting the whole thing back. The locking lid actually stays shut in his backpack, which is more than I can say for our last bottle.

My daughter flips the locking lid open and shut about fifty times a day and it's still holding up fine. The straw means she can drink without tipping it, which cut way down on spills in the car.
