YETI Rambler 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.

Okay, "best ever" is a bold claim, but when it comes to insulated tumblers, the YETI Rambler 20 oz with the MagSlider Lid is definitely a frontrunner. I've owned other insulated tumblers, cheaper alternatives, and even some that look almost identical, but nothing quite stacks up to the overall performance and durability of this YETI.What makes it so good? Let's break it down:Insulation Powerhouse: This is where the YETI really shines. Whether you're keeping your morning coffee piping hot for hours on end or wanting iced tea to stay refreshingly cold in the summer heat, the double-wall vacuum insulation works wonders. I've left ice in mine overnight and still had ice water in the morning - that's impressive.Built to Last: The stainless steel construction is incredibly robust. I've dropped this thing more times than I care to admit (on concrete, no less!) and it barely has a scratch. It feels solid and well-made, a true testament to YETI's reputation for durability.MagSlider Lid: Simple but Effective: The MagSlider lid is a game-changer. It's simple to use, offers a decent level of spillage resistance (though not completely leakproof), and the magnet makes cleaning a breeze. No more fiddling with intricate mechanisms or dealing with hard-to-clean crevices.Easy to Clean: The wide mouth makes cleaning a breeze. It's dishwasher safe too, which is a huge plus for convenience.Versatility: From coffee and tea to water, smoothies, and even the occasional adult beverage, this tumbler can handle it all.However, it's not perfect:The Price Tag: Let's be honest, YETI products aren't cheap. The Rambler 20 oz is definitely an investment. You can find cheaper options, but you often sacrifice performance and durability.Not Completely Leakproof: While the MagSlider lid offers some spillage resistance, it's not completely leakproof. If you're tossing it in a bag, I recommend finding a different lid.Can Be Heavy: When full, the 20 oz size can be a bit hefty. This might be a concern for some, especially for those with smaller hands.Overall:Despite the drawbacks of price and slight leakiness, the YETI Rambler 20 oz is a top-tier insulated tumbler. Its exceptional insulation, unmatched durability, and easy-to-use design make it a worthwhile investment for anyone who values keeping their drinks at the perfect temperature, wherever they go. While "best ever" might be subjective, it's definitely one of the best, and I highly recommend it if you're looking for a reliable and long-lasting tumbler. 4.5 out of 5 stars.

These are habit forming! I haven't used this one yet but if it's anything like it's cousins it's a keeper! I thought this size would be too big for my coffee but it's not. Barely fits under my coffeepot spout with the tray removed but I've come to enjoy drinking from these yetis! The colors are lively and can set your mood, calm, pleasant, peaceful, lively, fun loving, free, excited, there's no limit . . . Holds ice forever, keeps hot almost that long. Now don't come over here wanting MY cups! You go get your own! I'm going broke but I'm addicted.

Got this tumbler as a gift for my father in law and I think he’ll love it! I like that it came wrapped in plastic to avoid any scratches during shipping. The lid has great suction which I imagine will be great at preventing any spills. It comes with a sticker, an instruction sheet with washing directions, and a warranty slip which I think he’ll really appreciate. The colors are nice and the cup itself is just pretty in my experience and opinion. Since it’s a gift, I can’t put the insulation to test but it looks well insulated and it has a warranty in case it doesn’t.

I got this for my wife and she loves it because it's cute and keeps beverages hot all day. One thing to keep in mind is that these are not leak proof, so be mindful of that. It's a trade off to be either spill proof or have a lid that's easy to clean. I have a tumbler that is spill proof and it's impossible to clean the lid sealing mechanism and that is just gross. I'll take not spill proof over uncleanable grossness.
