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

The YETI Rambler 20 oz tumbler absolutely lives up to the hype. From the moment you pick it up, you can tell it’s built to last—solid, durable, and designed with real everyday use in mind. The insulation is outstanding. Hot drinks stay hot for hours, and cold beverages stay ice-cold even in warm conditions. I’ve left ice in it for an entire day and still had some left the next morning—very impressive. The MagSlider lid is a great feature. It’s convenient, easy to use, and helps prevent splashes, especially when you’re on the go. While it’s not 100% leakproof, it does a great job for normal use like commuting or working at a desk. The size is perfect—fits comfortably in most cup holders and has a great capacity without feeling bulky. The finish also holds up well over time and resists scratches better than expected. Overall, this is one of those products where you truly get what you pay for.

This is the best cup I have ever used, so much so that I use it for my everyday cup of coffee at home rather than a mug. It keeps drinks both hot and cold for so long. They are a little more expensive than other options, however I've had mine for 5 years and it still holds up and works like when I first purchased it. It is the perfect size, fits in a cupholder. It can be easily disassembled and put in the dishwasher.

Yeti cups are awesome. Pretty colors, no sweat drips on outside (great for Florida), Keeps drinks and ice cold (even left over night still ice in the cup). I have several in numerous colors. Dishwasher safe!!!

This is the 5th Yeti that I own. They never disappoint for keeping cold things cold and keeping hot things hot. They are expensive but worth it to me.

Now I know why they are so good. Keeps my drinks cold for hours. Great size and fits my car cup holder. Over all great product.

Love, Live, Love this tumbler!! The color is beautiful. I don’t usually like pink but, I’m very satisfied with this color.

Durable, cleans easily and keeps drinks COLD! Pricier than knock off brands but well worth the investment. You won't be disappointed.

The Build & Insulation As expected from YETI, the build quality is top-tier. The 18/8 stainless steel construction feels substantial in the hand and is puncture- and rust-resistant. The double-wall vacuum insulation performs exactly as advertised: Heat Retention: Keeps coffee piping hot for hours, even in freezing temperatures. Cold Retention: Holds ice remarkably well, making it perfect for long summer days. No Sweat Design: The exterior remains dry and easy to grip, regardless of the internal temperature. The MagSlider Lid is a standout feature. While it isn’t 100% leak-proof (don't toss it upside down in a backpack), the magnetic sliding mechanism is incredibly smooth and makes cleaning a breeze since the magnet pops right off. The "20 oz" Catch Here is the most important takeaway for daily use: this is functionally a 16 oz tumbler for transportation. While the vessel itself technically holds 20 ounces of liquid when filled to the absolute brim, that measurement does not account for the displacement of the lid. Because the MagSlider Lid sits deep within the rim to create a secure seal, you have to leave a significant amount of headspace to prevent overflow when closing it. If you are looking to fill this up at a coffee shop or at home and then put the lid on for a commute, you can only really store a 16 oz drink. Filling it beyond that point results in coffee splashing out the sides the moment the lid is pressed into place. The Verdict The YETI Rambler 20 oz is an over-engineered, aesthetically pleasing, and highly effective piece of hardware. However, if you specifically need to transport a full 20 ounces of liquid with the lid on, you may want to size up to the 30 oz model. If you’re comfortable with a true 16 oz capacity for mobile use, this remains the gold standard for tumblers. Pros: Indestructible build quality. Superior thermal insulation. Dishwasher safe and easy-to-clean lid. Cons: Functional capacity is only 16 oz when using the lid.

Original and so good

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!

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.
