Does the Kelso prevent spills when the tumbler is tipped over?

Yes, and you don't need to remember to close the lid! The Kelso tumbler has a valve in the spout, which lets water flow freely when kids are drinking, but stops spills if the tumbler is tipped over.

Is the tumbler easy to clean?

Yes, both the spout on top of the lid and the inner straw underneath the lid are removable to make cleaning easy, and the parts are all dishwasher safe.

How old should my child be to use the Kelso tumbler?

We recommend this tumbler for kids age 3 and up.

What kind of drinks can go in the Kelso tumbler?

The Kelso tumbler is perfect for everyday cold beverages like water, milk, or juice. Thick smoothies are a little more difficult to drink with the valve, while carbonated drinks can build pressure and push liquid up through the straw.

Can I travel with the Kelso?

The Kelso tumbler fits in most car and stroller cup holders for on the go convenience. We don't recommend putting the Kelso tumbler in a bag, as pressing on the soft spout can open the valve and allow drinks to flow out.
