YETI Rambler 30 oz Stainless Steel Vacuum Insulated Tumbler w/MagSlider Lid, Black

The 30oz Yeti Tumbler is one of those products that reminds you why the Yeti brand has such a loyal following. Their product line is huge—coolers, bottles, mugs, accessories—and while the price tag can feel like an investment, the performance consistently justifies it. This tumbler keeps drinks exactly how you want them for hours. Hot coffee stays hot well into the afternoon, and cold drinks stay icy long after you’d expect. The insulation is genuinely impressive, and the durability is exactly what you’d expect from Yeti. It’s built to last, even with daily use and the occasional drop or rough handling. If you’re looking for quality, durability, and long-term reliability, Yeti products are absolutely the way to go. Just be ready for the higher cost—but in my experience, it’s an investment that pays off every single day.

My every day cup! The perfect size for me. It's easy to use, clean and fits in my car cup holder. It's simple design is nice, strong and great for keeping both hot and cold drinks. I'm an ice chewer and I fill this cup up, fill my favorite coconut water and it doesn't water it down! When I make tea, it's HOT still even with the lid off and definitely keep warm for a long time. Great purchase and worth the price.

My husbands favorite Christmas present this year. Absolutely love the color and true yeti sturdiness. Keeps everything cold or hot for hours. Love the detachable closure so you can really clean it thoroughly too.

After using this 30 oz Rambler for a few weeks, this tumbler is an absolute game-changer. First off, the build quality is exactly what you'd expect from YETI: incredibly sturdy and premium-feeling. The stainless steel construction feels rugged and durable, and the MagSlider lid, while not completely leak-proof, is brilliant for preventing splashes and is super easy to clean. But the real magic is the insulation. It is truly phenomenal. I can pour in hot coffee at 7 AM, and it's still warm by noon. For cold drinks, it's even more impressive – I've left ice water in a hot car for hours, and the ice was still intact. No condensation on the outside, ever! It fits perfectly in my car's cup holder, which is a huge plus for my daily commute. The 30 oz size is perfect for staying hydrated throughout the day without constant refills. Overall, this is a top-tier product that lives up to all its promises. It's worth every penny and then some. If you're on the fence, jump in – you won't regret it! Highly recommended!

For years, I held off on buying Yeti drinkware because of the price. Last year was a game-changer for me when I bought my first. Long story short, I am now a Yeti-holic. I now almost always use only Yeti insulated beverage containers to drink from. The 5-star insulation aside, I love that I can drink something icy cold without any condensation outside the container. I find this especially useful in the car. Unless you have a Yeti beverage container with a handle, it should fit in your car's cup holder. These beverage containers soon became a favorite present for me to give to others. You will simply not find anyone who is not delighted to receive one. Lol, then the recipient wants to buy more, because others in the household keep using theirs. While it is not necessary, I find it helpful to keep my frequently used ones in the fridge to extend the insulation time. If used outdoors in the summer, it does react somewhat to ambient temperature. It will still keep beverages colder than anything else on the market, but not as long as it does indoors. Keeping it out of direct sunlight and, if applicable, closing the sipping tab helps when outdoors. Easy to clean with a large variety of colors and sizes. No taste interference with your beverages at all.

Already have one in plain stainless, just wanted to add one to my rotation (clean/dry one while using the other). As usual, Yeti gets the insulation right, to keep cold things cold (haven't needed to try hot things.) With the black coating, this one is more "grippy" than my much, much, older slick stainless Rambler--which still works fine. You do pay a Yeti price for these, but you get solid, Yeti quality. The Magslider is great because you can completely remove it for cleaning, and it just "works." Note: I don't drop, beat, or bang these around, so I can't comment on abuse-longevity.

It is one of my favorite mugs to take with me. However, the lid needs improvement; heat escapes through the top of the mug. Additionally, if the cup tips over, it will leak. For these reasons, it is priced higher than it should be.

Awesome product @ good price, now my daily cold drinks stay cold for an entire day
