Compatible with Yeti Lids 20 oz Replacement Lid, 10 oz Lowball, 10 oz Mug, Ozark Trail Tumbler Lid and Other Replacement Lids for Tumblers. (20 oz 1 Pack)

I guess I have "new" 30oz Rtic tumblers. This top is too small for New Rtic 30 oz.

The Kind...That "stay's Open while using" !

I got a Serengeti mug and dropped it the same day. The lid completely broke and the lip of the metal tumbler dented. I couldn't find Serengeti specific replacement lids so I ordered these. It's not a perfect fit, but that worked for me because of the dent in my cup. The lid fits well enough to prevent spilling.

Exact fit.

So, couple things need to be addressed with this item. First the lid is on a track, and can't be removed, making it difficult to clean and disinfect.I did get a few months of use out of it however, and noticed it also does not have any kind of air hole, so as you are drinking the flow of your beverage becomes minimized over time.The lid itself eventually broke, for reasons I can't explain. I'm a bit rough on my thermos, but it was mostly exposed to normal, daily wear and tear. The inside bevel of the track for the lid cracked assuming due to brittle plastic.. Problematic, as there is nowhere for the plastic to fall but directly into your drink.Poor quality product and design overall and not safe, look elsewhere.

I bought these to replace the lid on a dragonfly cup I purchased that cracked when I dropped it. It fits on the smaller size stainless steel cup. Make sure to measure the diameter of your cup before ordering as there are 2 sizes. The 1st set I ordered arrived with the product packaging bag torn open and 1 lid missing. It should never have been mailed out like that. The replacement set came quickly & was perfect so no stars lost.

I bought these for my RTIC tumbler. Fit nicely, but the rubber gasket is not secure. It comes loose and does not stay in place. I thought maybe my tumbler may have been dropped and bent, but the same results on a new tumbler. All three have the same issue.

These were a perfect fit for my YETI cups.
