The new model for the Klean Kanteen sippy cap is deemed far better than the others. This is because the new cap is child-friendly, and can be eaily used by toddlers. Additionally, it is softer than other models. The cap is also spill proof.
Its attachment loop means that it can be quickly fastened to a variety of objects, including bikes and rucksacks. The cap fits in all of the Kanteen Classic sizes as well, and has a cover to protect it from dust.
The cap contains no toxins, and it is also safe to put in a dishwasher.
