Straw lid for Yeti Rambler Water Bottle 18 26 36 64 oz, Replacement Cap Straw Cap for Yeti 18oz 26oz 36oz, Lid with Straw and Brush and Flexible Handle 

This lid fits my 40oz Yeti bottle very well, and does not leak. The carry handle works very well, feels durable, and is very comfortable. I've previously only used the Yeti chug cap that came with my bottle, and it's difficult to fit my fingers through the carry handle part. Not really an issue if you have small hands, but I've also had to replace that cap twice in the last year over the same issue with weak top cap threading. The only seem to last me a few months. This lid seems like it will hold up a lot better though. I can also screw this cap on even when my bottle's almost filled to the brim, as long as I have the straw part of the cap extended. With the Yeti chug lid, I had to remember to take the top cap off if my fill level was near the threads, otherwise it would spill everywhere. This makes things a lot easier.

Very nice lid.No issues.Fits Rtic as well.

Great fit, no leaks, easy to clean. It took a couple falls but still look like new. Only drawback was that straw was a little to big so it bend in the bottle

Love fits perfect

This fits as a replacement for 36 oz rtic tumbler (rtic does not make this size anymore or lids for ) Works great for what I needed
