Staying Cool In The Cabo Sun!

What is not to like about this cup? I was on vacation, sitting by a pool and the waiter keep filling my cup, they knew which was mine, and my drink remained ice cold in the Cabo sun. There was in fact many Yeti cups being filled and the contents being enjoyed ice cold.🥳

Yeti Insulated Tumbler

This cup is great! I used it for my hot & cold drinks. I really like how it maintains their temperature for long periods of time

Impressive Durability

* On May 18, 2026, my kitchen was destroyed in a fire. In the days afterward, as I sorted through the damage, I was shocked to discover that my Yeti tumblers had survived. They had been exposed to extreme heat, yet they remained intact and usable. While they showed signs of what they had been through, they did not warp or melt. Unfortunately, several tumblers I owned from other brands weren't as fortunate—they warped badly or melted completely and had to be discarded. Seeing the difference firsthand gave me a whole new appreciation for the quality and durability of Yeti products. I bought them because they perform well for everyday use, but I never expected them to withstand conditions like those created by a kitchen fire. When so much was lost, it was genuinely impressive to find something that endured. My experience has made me an even bigger believer in Yeti's craftsmanship and durability, and I'll continue recommending their products to friends and family.

Perfect Size, Shape, And Lid

Love this mug for its size (small enough for a cup holder but not too skinny), shape with no handle, and lid.

Great Iced Coffee Tumbler

Love the color and love that these cups stack and fit in my Keurig Iced Mini machine without issue. I do feel like there is a little room for a slightly larger overall diameter to get a couple more ounces in these without impacting usability too much. But that is just wishlist stuff.

Not As Pictured - Must Buy Lid Part Separately

Does not come with magslider for lid, even though pictured. You have to buy that part separately. Sad
