While the market is full of vacuum-insulated vessels, the YETI Rambler 20 oz offers standout properties that set it apart from the rest.

YETI is best known for its coolers. As you can see, the company calls Rambler Tumblers “personal drink coolers.” Made from an 18/8 stainless steel with vacuum-insulated walls, the YETI Rambler 20 oz regulates ambient liquid temperatures inside. The lid is made from BPA-free plastic that snaps onto the 20 oz or 30 oz version of the cup. You can also use the snap-on lid with the Rambler Lowball, a mini version of the cup we’ve grown to love.

A Little About YETI

In 2006 YETI Coolers was founded with a simple mission: To build the cooler you’d use every day if it existed. It would be one that was built for the serious outdoor enthusiast rather than for the mass-discount retailers. It could take the abuse we knew you’d put it through on camping trips and on the water.

The goal was to make a cooler that simply wouldn’t break. They decided early on that product innovation would come from necessity and firsthand experience — not from market research and data analysis. And they’d never sacrifice quality for a few extra bucks. Because having your cooler’s lid cave in when using it as a casting platform should never be part of anyone’s fishing trip.

Today it is the cooler of choice for outdoor enthusiasts, pros, tailgaters, and backyard barbecue kings. And that still gets us fired up. Ultimately, life is about having a good time doing what you love. And for the folks at YETI, that’s being outdoors hunting whitetail, catching a tarpon on the fly, and spending time with families and buddies. They’re wild at heart. So their coolers couldn’t be anything less.

We Tested It Out

YETI Rambler 20 oz - Tested It Out

We had to see for ourselves if the YETI Rambler 20 oz was as good as the reviews said. And we’ve got to say – we were pleasantly surprised with what we found. The perfect on the go cup is one that can hold both hot and cold liquids and keep them at their desired temperatures. We took the rambler out for its first test, coffee.

The Hot Coffee Test

If you’re anything like us, you drink way too much coffee in the morning – about three cups to be exact. During cold winters, nothing is better than pouring your coffee into a travel mug and having something warm and caffeinated to accompany you on your way to work. Want to know the best part about using the YETI Rambler 20 oz? You won’t have to reheat your coffee. If anything, your coffee will probably be too hot by the time you get to work. This mug seriously delivers when it claims to hold temperatures.

The Cold Drink Test

Do you also pour a drink and then forget about it when you’re doing something around the house? We’ve always thought of ourselves as multi-taskers but maybe this is the area where we fail. You come back and your drink is all warm. But hey, don’t worry too much. The YETI Rambler 20 oz has solved this problem for the both of us. How? It actually keeps cold drinks cold. Walk away and forget about it for hours. It won’t matter. When you come back, your drink will be just as cold as when you first poured it. Magic.

Minor Flaws

The only minor flaw we noticed in the YETI Rambler 20 oz is the design of the lid. It spilled a few times while we sipped; some sort of closing mechanism would be helpful. If you’re taking this tumbler along on a road trip just don’t fill your cup to the bring and you should be fine. Avoid the sloshing around.

What Travelers Are Saying About the YETI Rambler 20 oz Stainless Steel Vacuum Insulated Tumbler

At the time of writing, the YETI Rambler 20 0z Tumbler has over 5,300 reviews on Amazon with a four and a half out of five-star rating. This is such a great cup for when you’re on the go. Fill up some hot coffee in the morning or bring something cold with you on a hot summer’s day. Overall, travelers absolutely love this Tumbler. As far as the coffee temperature maintaining capabilities, we were impressed.

Other Options

While the YETI Rambler 20 oz is the perfect size for an on the go drink, YETI also offers the rambler in two other sizes that really come in handy. Check out these tumblers.

10 oz Lowball

The Rambler 10 oz. Lowball is the ideal drinking companion at the deer lease or around the campfire. Whether it replaces your morning coffee cup or serves as your nightly whiskey glass, the Lowball's double-wall vacuum insulation will keep your hot drinks hot and your cold drinks cold far longer than standard drinkware. And unlike your favorite bourbon glass, this Lowball will never shatter or leave a ring on your coffee table.

30 oz Tumbler

Days on the dock are made better with the Rambler 30 oz. Tumbler. It’ll keep your dinnertime drink cool well past sundown or your coffee nice and hot throughout the morning. The Rambler 30 oz. Tumbler is made of 18/8 kitchen-grade stainless steel, has double-wall vacuum insulation, and no sweat design. This means that you’ve got one heavy-duty, over-engineered stainless steel tumbler on your hands with the Rambler. It’s dishwasher safe, BPA-free, and ready for just about anything.

Thermos Stainless King

We’re sure you know all about the Thermos brand. After all, they’ve been around for more than 110 years. Just like traditional containers, heat and cold find their way in through convection.

Make sure that before you use it and as soon as possible after each use, make sure you wash all parts of the mug with warm, soapy water. Rinse all of the parts thoroughly and let them dry. While this mug is easy to wash, I’m conflicted about the assembly. There are several moving parts you have to put in place for it to function before each use. Overall though, this mug has more pros than cons. It’s also top-rack dishwasher safe.
