RTIC Essential 40 oz Leak-Resistant Lid Ceramic Lined Tumbler, Black

This is exactly what I have been waiting for—a ceramic-lined insulated drink mug. I dislike the metallic taste that eventually seeps into my coffee. I definitely recommend this brand. Since purchasing this mug, I have bought several more in different sizes. All are fantastic!

I like that it keeps cold drinks cold for 24 hours. I also like the larger size it comes in. The shape is good because it fits in my car well. Great cup without breaking my budget!

I like this cup for cold items however, I purchased it for hot drinks. It was described as Ceramic inside which is what I was looking for. I am disappointed because the inside is ceramic paint and not ceramic. My coffee tastes like paint. I can not use it for the purpose which I purchased it. It's a nice cup but I have plenty of cups for cold drinks. I wanted a ceramic lined travel cup that is like a coffee cup inside not paint

Love this cup and the size. Love the screw on top in case I knock it over, no spills. Love the ceramic liner.

The ceramic lined Rtic Tumblers keep the ice much longer and the water much more Fresh Tasting!! And we received Awesome Value for the price through Walmart online!!

The ceramic coating does take away the metallic taste in the tumlber and give it a fresh taste similar to drinking around of a real glass. I used tumblers for years and am pleasantly surprised in the difference in my tea. Now I have a cabinet full of tumlers I don't drink out of. The ceramic looks kinda dull and it doesn;t come with a straw. Most straws are to short or metal.

These are fantastic. Fits into a cupholder but still holds 40 oz. The new screw on lids are better that the old ones.

Literally the best tumbler ever. I've owned all the top brands, and never found one that I felt was perfect. Until now. Screw top lid means it won't pop off if it tips over, the seal on the sipper top is crazy tight. You can turn it upside down and shake it without worry as long as you don't fill past the inner threads before screwing the lid on (found out the hard way lol). AND it's 40 oz, AND it fits in a cup holder. Literally checks every box. I could take or leave the ceramic coating, but that's there too for the people that care. Can't recommend this cup highly enough. Sadly, no one is paying me for this stellar review. And while I wish they would, I'm just truly impressed, so I'm letting y'all know.

It is indeed spill proof and drink stayed cold all day.

I bought one for my husband and myself after having the top come off of our previous cups with press on lids too many times. The last draw was when I picked the old one up while driving only to have it spill all over myself. No more problems with these and they will still have ice in them over night.
