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

I’m extremely happy with this YETI Rambler. The quality is excellent, and it keeps my cold beverages ice cold for around 12 hours. Even after several hours, there’s still ice left in the cup, which is impressive. It also fits perfectly in my car’s cup holder, making it great for commuting, running errands, or road trips. The tumbler feels sturdy, is easy to clean, and the lid helps prevent spills while on the go. The color is beautiful, and it looks just as nice in person as it does online. Although it’s more expensive than some other tumblers, the performance and durability make it well worth the investment. I highly recommend it to anyone looking for a reliable, high-quality insulated tumbler.

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 Works Let’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 Quality Like 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 Effective I 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 Everywhere This 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 Cleaning Everything 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 hand Cons: • Not leakproof (though the MagSlider is splash-resistant) • Pricier than off-brand tumblers, but you get what you pay for ⸻ Final Thoughts If 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.

Love everything about it. I always take a glass of water to bed. I must take medication during the night so it doesn’t’ effect other meds I need to take later. The tumbler is very sturdy, great looking and keeps my water cold. The magnetic cover over the spout works so easy. It can be removed to clean the lid thoroughly. I like that the lid does prevent most of the water from leaking out if it is knocked over. It is not water tight. This Tumbler is great if you need a refreshing drink during the night.

The capacity is really big, which I love. The lid isn’t completely leakproof, but I’ve kept it in my car and even on bumpy roads, no water spilled out. I’m very happy with that. It also keeps drinks hot or cold for a good amount of time.

Love my Yeti. keeps my coffee hot all morning at work and the cool design looks nice on my desk. I have many different Yeti coffee cups but this one fits in my car console and the size is great for taking to work. It isn't so tall it gets in the way the new lid slides easy and my coffee never has a metal or bad taste.

This is my second Yeti tumbler. My first one still works, even after dropping it a few times. I liked my first one sooo well I bought a second one in a brighter color. When I misplace this one I can spot it right away. Love that Pink. It keeps my water cold and fits in my cupholder and is easy to clean.

I bought this because I wanted a good cup, and now I understand the hype. It keeps drinks cold, doesn’t leak, and can handle being tossed around like it’s part of my daily survival kit. It has survived car rides, workdays, and being forgotten on the counter. A little pricey, but it’s basically the superhero of drink containers.

Sturdy, well built, retains hot coffee for hours. May want it to be drinking hot before placing it in Rambler. Fits nicely in car cup holder. Seals well and magnetic opening is easy to open. Looking forward to using it in colder weather.

Honestly, not sure what I did before I had this tumbler. It looks great, holds temperature well and is surprisingly easy to clean (just chuck it in the dishwasher and it comes out spot loss). It’s not leakproof, but it’s not marketed as such, so no complaints there. The magnetic, removable MagSlider lid is genuinely useful and pops off easily for washing. I was a bit worried about the size at first, but it’s actually really comfortable to hold and doesn’t feel bulky or heavy at all. It works just as well for hot drinks as it does for cold ones, whether that’s a morning coffee or something chilled like a beer or cocktail. Easy to drink from too, it feels more like using a regular mug than a travel cup, which makes it a joy to use daily. Solid bit of kit and definitely one of those things you end up using more than you expect, and of course it makes a great gift!

Love it! The design is beautiful, my kind of beachy style, doesn't feel grainy in your hands, love that it's dishwasher safe, I ordered the size down previouslt and it was really small the pictures on that cup doesn't give the sizing of the cup properly. I got the bigger size, so glad that I did. The only issue is the lid, if it tips over coffee does spill out. Not quite spill proof. The lid it supper easy to clean, the part the slides open and closed is magnetic. Yeti does have different colours so they can be swapped out. Over all fantastic cup, definitely recommend. Keeps the coffee hot for a good period of time.

YETI!!! What more can I say?? Bought this one for work as I’m a trucker. This will keep your drinks hot or cold for most of the day! Well made and great durability, love the super tough lid and it just feels good quality as well! A must have for any traveller

Muito bom!!!

Very impressed. Keeps contents hot for 4 hours. Has to be kept upright as lid does not seal but this was disclosed in the description.
