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

I’ve had the 20oz tumbler for about 6 months now and I love it so far. Yeti is an expensive brand of course, but the up front investment is definitely worth it and you definitely get the industrial quality that you pay for.I use it mainly for iced coffee, sometimes hot drinks, but iced drinks are where it really shines.Pros:-Practically indestructible-Easy to clean, dishwasher safe-Great insulation-Fits in standard cup holder-Easy to hold and carry (I have small hands)-Sleek, minimalist design-Functional lid and closure-20oz is a perfect size - not too small yet not too cumbersomeCons:-Not spill/leak proof-Does not retain heat as well as it retains ice and cold liquids

Yeti cups are great in keeping cold things cold, or hot things hot for long after an ordinary cup would do so. The lid design is great with the magnetic slide that helps reduce sloshing when one is not actively drinking. It's not leak-proof, I've gotten my bag when with the cup has accidentally fallen sideways. That being said, as long as you keep it upright, it's pretty safe from spills.Recently, I had an occasion to appreciate Yeti's great customer service on another cup that had a peeling finish. Yeti's website provides a way to provide the individual serial number of the item (Yes, each of their cups has a unique number) and to describe the problem. I was immediately offered the opportunity to get a replacement cup (in a different finish) and could either get the cup first (and return the defective one), or mail in the cup first and then get the replacement. It all worked really smoothly, and so if I ever have a problem with this particular cup, I have confidence Yeti will address the issue.

Yeti is such a durable and well designed brand, it’s well worth the investment, especially on sale! The 20oz is the perfect size for running errands, fits right into the cup holder, comfortable & easy to carry, drinks stay super cold for hours, the lid keeps a perfect seal even after months of running through the dishwasher, no scratches or peeling either, a great way to get away from plastic water bottles

Why did you pick this product vs others?:Quality and design is superior to any other insulated mug I have tried. Keeps coffee warmer, longer. The magnetic slider is awesome! The powder coating simply lasts and takes abuse from drops and the dishwasher like you wouldn't believe. It refuses to chip or flake.Is it perfect? No. Be aware that the lid and/or magnetic slider can pop off from higher drops. The lid is not completely leakproof as well. You cant just throw it into a bag like a Contigo mug. Not a big deal for me. I love it!

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.

The YETI Rambler 20 oz Tumbler in Key Lime is not just a drink vessel; it's an investment in temperature retention and style. YETI's legendary vacuum insulation truly lives up to its reputation, keeping my coffee piping hot for hours on my morning commute and my iced tea refreshingly cold throughout the entire workday, even when left in a warm car. The stainless steel construction is incredibly durable, shrugging off bumps and drops, and the Key Lime color is vibrant and eye-catching. The MagSlider lid is a brilliant design feature, adding an extra layer of splash protection and making it easy to clean. While YETI products are premium, their performance and longevity make them absolutely worth it.
