The Flip Spout Summit Lids are replacements for the adult "Summit" style bottles and will also fit the Boulder, Big Foot, Boss, Tritan and Perk bottles to give you added value and versatility. A straw and ruler are included so you can easily trim to the length you need. We suggest you err on the side of cutting a little longer, as you can always trim more if needed. If you have an older bottle with 2013 stamped on the bottom or not dated, this top may not fit.
If you are not sure if this lid will fit your EcoVessel bottle, please email customer service email@example.com with an image of your bottle. We will not be held responsible for incorrect purchases.
I have several Eco Vessel bottles and the interchangeable lids are fantastic.
This is a great addition to my Boulder bottle, i like being able to chose between the screw cap lid and the straw lid.
