Please scroll down for a list of bottles this lid fits. When you click on the name, it will take you to a picture of the bottle. This top will only fit the linked products and is not compatible with other models. The included straw is cut to fit our tallest Eco Vessel bottle. A ruler is included with the names and sizes of Eco Vessel bottles clearly marked, so you can easily find your model and use scissors to cut the length you need. We suggest you err on the side of cutting a little longer, as you can always trim more if needed.
