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.

LOVE my YETI, especially this style and color! Fits in my cup-holder in the car perfectly. The color is a rich gold and as with all Yeti products I have had (which is a lot) it’s proven to be very durable, keeps my drinks hot/cold and it easy to hold….not too heavy. No leaking lids either so this is perfect!

The YETI Rambler 20oz with MagSlider Lid is hands down one of the best travel tumblers I’ve owned. It keeps my coffee hot for hours and my iced drinks cold all day — no weird metallic taste, no leaks, and no condensation on the outside.The MagSlider lid is a great feature. It’s easy to slide open and closed with one hand, and while it’s not completely leakproof if tipped, it does a solid job preventing splashes and spills while driving or walking.The white finish is clean and modern, and it holds up really well without staining or scratching. It fits perfectly in my car’s cup holder and is easy to clean too.Totally worth the price for the quality and performance. I’ll probably end up getting another one in a different color! I have 4

I am not going to repeat the glowing reviews already submitted for this product but I do want to make this comment. This is my first purchase of a YETI product and in this throw away society that we live in today I was completely surprised with the quality of the YETI Rambler 20 ounce Tumbler. It is rare today to find any high quality products in the market place, especially any made in China but this is the exception. If you purchase the Rambler Tumbler I highly recommend purchasing the optional handle —- you won’t regret it. I am so thankful that I spent the extra money to purchase this product —- thanks goes to all the glowing reviews.

I’ve been using the cup every day for a year now. Not a dent. Not a scratch. Keeps my coffee and teas hot for 5 hours. Not super heavy. Great for every day use and even better when camping to make sure your morning coffee stays hot! I also like how you can change out the sliding seal on the top to prevent spilling and customize the cup!

Delivered right on schedule.The availability of these camo tumblers is spotty, and often at exorbitant prices owing to that scarcity. I was delighted to buy two of these at a more reasonable price!!It’s a Yeti. No more need be said!

My main problem is that it does too good of a job. If I forget to open the lid, or the slider, my coffee’s too hot to drink an hour after it was poured. Great vacuum insulator, easy to clean, not too big for a cupholder - 20oz is the perfect size.

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.
