YETIRambler 20 oz Stainless Steel Vacuum Insulated Tumbler w/MagSlider Lid

The media could not be loaded. After using the YETI Rambler 20 oz Stainless Steel Vacuum Insulated Tumbler with MagSlider Lid for the past few months, I finally get the hype. This isn’t just another stainless steel cup — it’s a well-thought-out, rugged, and practical piece of gear that fits perfectly into daily life. Whether you’re commuting, working at a desk, road-tripping, or just hanging out at home, this tumbler checks every box.Temperature Control That Actually WorksLet’s start with what matters most: performance. This thing keeps drinks hot or cold for hours — and I mean hours. I’ve filled it with coffee at 8 AM, forgotten about it until almost noon, and the coffee was still warm enough to drink without reheating. On the flip side, ice water stays cold well into the afternoon, even if it’s sitting in the sun or inside a hot car.YETI’s double-wall vacuum insulation really delivers. I’ve tried cheaper tumblers before, and they just don’t compare. With the Rambler, I never have to worry about my drink turning lukewarm too soon.Durability & Build QualityLike everything YETI makes, the Rambler is overbuilt in the best way. The stainless steel feels thick and solid — no flexing, no dings from regular use. I’ve accidentally dropped it a couple times, and aside from a scuff here and there, it’s held up perfectly.The powder-coated finish (I got mine in navy) is grippy, doesn’t sweat, and still looks brand new even after daily use. You can tell this thing was designed to last years, not months.The MagSlider Lid — Simple But EffectiveI was a little skeptical of the MagSlider lid at first, but it’s grown on me fast. It doesn’t make the cup leakproof, but it does a great job keeping splashes and spills to a minimum — especially when driving or walking with it in hand. The magnetic slider is smooth and pops off easily for cleaning. It’s one of those small features that actually makes a difference.For anyone wondering, you can buy a totally leakproof lid separately if you need to toss this in a backpack, but for everyday use, the included lid does the job really well.Fits EverywhereThis may seem minor, but the size is perfect. The 20 oz Rambler fits in cup holders (car, stroller, office chair — you name it) and doesn’t feel bulky in your hand. It holds just the right amount for a decent coffee or a generous pour of iced tea, without being overkill.Ease of CleaningEverything comes apart easily for cleaning, and there’s no weird corners or plastic seams that trap gunk. It’s dishwasher-safe, too, which is huge. I’ve run mine through dozens of cycles and haven’t noticed any degradation in the finish or performance.⸻Pros:• Excellent temperature retention for both hot and cold drinks• Durable stainless steel construction that holds up to daily abuse• Fits most cup holders — great for travel and commuting• Powder coat finish resists chips and sweat• Easy to clean — dishwasher safe and low maintenance• Smooth, effective MagSlider lid helps prevent spills• Feels premium and well-balanced in handCons:• Not leakproof (though the MagSlider is splash-resistant)• Pricier than off-brand tumblers, but you get what you pay for⸻Final ThoughtsIf you’re tired of lukewarm coffee or watered-down iced drinks, the YETI Rambler 20 oz Tumbler is worth every penny. It’s the kind of product that quietly improves your day-to-day life — you stop thinking about it because it just works. Between the rock-solid insulation, the slick MagSlider lid, and the build quality that feels like it could survive the apocalypse, this tumbler delivers exactly what you’d expect from YETI. I honestly don’t see myself needing to buy another tumbler again.

I love it! I always loved Yeti and the sizing they carry. The insulation is top notch! I love this size is ideal for my coffees in the morning. The lid just goes up and down be sure to clean the plastic band surrounding it for better clean, especially if you make shakes. Easy use and you can see inside the tumbler with the clear view of the lid. Totally durable and I need it in like six other colors

My whole family has one now. We used to always use Thermos coffee mugs but they’re harder to keep clean and after a while get banged up and ugly. Our Yeti coffee mugs hold up well, are easy to clean, and most importantly keep our coffee hot for hours. I like the color selections too.

Can can use it for a hot. Can you use it for cold. I have a few in different sizes. I bought this one because of the color. Baby blue I have one in SS that I have had for about eight years. I use it every day for water and it’s really large I am definitely a fan.

I got the stainless steel one and I love it. The mag slide clear top is great. It has a very good seal. Its large capacity holds and keeps plenty of coffee hot for hours. It’s rugged design and great looks makes it a great travel companion. Fits in a normal coffee cup holder. Couldn’t ask for more.Mick from Olympia

It’s a cup that keeps your drinks cold for hours and the build quality is top notch. Easy to clean and the magnetic cap is satisfying and simple. What more could you want? It’s 35 bucks for a cup, but hey - buy once, cry once.If I ever lose this cup I’ll quickly replace it with the exact same one. I love it.

Love my Yeti 30 oz. My husband drops things easily, especially coffee. This comes in handy for him. Also love it for trips while riding in the car. Purchased 2 of them and also the 10 oz.

I love this mug! It keeps things hot and keeps things cold...for many, many hours! Except for it being a bit pricey, I would give it all stars.
