I’ve used it for both hot coffee and iced water, and it’s incredible how it keeps drinks at the perfect temperature for hours.Hot drinks: My coffee stays piping hot for well over 6 hours. I love that I can take it to go in the morning and still have hot coffee by lunch.Cold drinks: I’ve tested it with ice water, and the ice doesn’t melt until after a full day! No more watered-down drinks, even in the summer heat.The build quality is top-notch – solid and sturdy, and it feels really comfortable to hold. The lid seals tightly, so no spills or leaks. Plus, the design is sleek, modern and light!I was skeptical about the price at first, but after using it for a while, I can honestly say it’s worth every penny. It’s durable, functional, easy to clean, and keeps my drinks at just the right temperature all day long. Definitely recommend it!

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

VERY CUTE. I waited for this color (since it's limited) for a good price and got them as soon as they restocked. It is dishwasher safe, but I personally handwash it to preserve the color. This was my first Yeti cup and it was worth it. Left my drinks very hot for a few hours and was able to enjoy my tea throughout the day.

This is our 5th to the collection of coffee mugs and safe to say we highly recommend! Having these for the last 5 years or so, I really like the feel and quality of the more recent ones. I am not sure if they've changed any of the materials, but it feels lighter and smoother if that makes sense. I love the cream color and the fact that the magnet is removable when we wash in the dishwasher. These Yetis keep my coffee hot for the first few hours and warm throughout the entire day which I cannot say about the rest of the coffee tumblers I have. While it is not entirely leak proof, the magnet and lid do stay on pretty tight. Love these and will continue buying and gifting!

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.
