Perfect fit! Now the life of my old, tried and true, vessel is extended! Although it's taking second place to the new one just purchased!

I was super-pleased to find these (with a little help from a friendly EcoVessel agent). All four of our kids have the older style bottles and we use them every day, so the straps on a few of them were broken. Not too stressful to get on and off-just make sure that when you slip the ring over the top of the bottle the small cap is bottom up! Not that I had any confusion with it, or anything!

Replacement for original cap. Warped the original after putting it in the freezer with the thermos. Fits great and fast delivery. Glad they make replacement parts!

This is my husband's second cap. The plastic broke on the first one.

This was a perfect replacement for my old top, which broke after a long time of carrying it every day by the handle. I was a little worried about fitting it over the lip, but it only took a little "encouragement" with a narrow tool, and it fit right on, just like the old one. Thank you!
