  • Description & Features

Any tumbler that's coming along for the ride needs to be tough enough to keep up. YETI's Rambler® 20 oz. is made from durable stainless steel with double-wall vacuum insulation to protect your hot or cold beverage at all costs. While the magnet on the included MagSlider™ Lid adds an additional barrier of protection for keeping drinks contained and preventing heat or cold from escaping, please note - this magnet component is not leakproof and will not prevent spills. Available in stainless and DuraCoat™ colors.

  • 18/8 Stainless Steel: Made with kitchen-grade stainless steel, so they’re puncture- and rust-resistant.
  • Double-Wall Vacuum Insulation: Keeps cold drinks cold and hot drinks hot until the last sip
  • Dishwasher Safe: Because no one needs more work to do
  • Outside 6 7/8” × 3 1/2”
  • Empty Weight 12.7 oz

Rated 1 out of 5 by from Very Leaky! I'm surprised this has so many high reviews because I feel there is a huge design flaw in the lid. My partner and I both received them for Christmas and neither of us will continue to use them because of how leaky they are. For a travel mug, you would expect to be able to walk with it, but the liquid comes right out of the lid even with the top closed. I'm used to having a sealed lid that I can throw in my bag, and I knew that this would not be the same, but I didn't realize how much hot coffee would be splashing out of the top as I walk. Would definitely not recommend for anyone who intends to move around with their mug.

Rated 4 out of 5 by from great but... love this cup and that i could buy the extra lid with the straw however I live in Canada and they do not offer registration for any Yeti products outside of the U.S. which is not very fair to me.. shouldn't they guarantee their products no matter where you live in the world?

Rated 4 out of 5 by from Awesome! But wish it was spill proof. I love this cup. Its perfect for a mom that doesn't always get to sit and drink a full cup of coffee at once. The only downfall is the lid is not spill proof. I knew that purchasing it, but didn't think it would be a huge deal for me because I just planned using it around the house. But I love it so much I take it everywhere now (sidenote: it fits great in a cupholder). When full, coffee will seep out of the lid if you hit a pothole or something and I've managed to spill it a couple of times with an armful of things, trying to get to the vehicle or in to work. If it had a spill proof lid I would give it 10 stars!

Rated 2 out of 5 by from Hot does not stay Hot! Yeti is suppose to be a great mug, VERY DISSAPOINTING. I was happy with my mug in the beginning, except after 3 months, it began loosing its capabilities to keep my tea hot. Even if I heated my mug up by pouring boiling water in it and letting it sit for 5 minutes, then pour my tea in it. I had intended getting one as a gift for my sister, but after seeing how it performed, I changed my mind. I would not recommend it for keeping things hot for more than 2 or 3 hours. There are better mugs out there at a much cheaper price. Sorry Yeti.

Rated 4 out of 5 by from Tumbler is fantastic, lid could use some work. The tumbler itself is amazing, and actually better than I expected. The lid, however....could use some work. I understand that it's not a "leak-proof" lid, however, even when it's closed, I can't keep it in my stroller cup holder because coffee splashes out of it continually. Despite washing my mug and lid in warm, soapy water immediately after use, as recommended, I have also noticed some buildup under the slider part of the lid, which is impossible to get to. I would love to see a better-functioning lid, that matches the quality of the tumbler.

Rated 5 out of 5 by from Happy with Purchase I really like the look of my copper mug. Easy to clean as well, what a great idea with the magnetic slider. Works better than my old travel mugs, keeping coffee hot from 8-10 am then it starts to dissipate. I also get busy and can forget my lid is open. I often am still drinking until noon. Fits in both my car's cup holders, as they are different sizes. I also am hoping this mug last's decades as I have had to repair ceramic ones and toss plastic ones. It makes me happy that you sell lids separately as replacements. I figure the body will outlast the lid. I asked for this mug as a gift after watching my spouse use his for a year now and he loves it.

Rated 1 out of 5 by from Product review I loved the idea of a Yeti, so I searched everywhere to find a beautiful purple one. Upon arrival I learned for keeping things cold it does great! For keeping things hot, which is what I use it mostly for, it misses the mark completely. I would say my coffee stays hot for 3 hours MAX. I am busy at work, and most days it takes me hours to actually finish my coffee. I have many cheaper travel mugs that stay hot for much much longer then my Yeti. The lack of a spill proof lid, or even a thermal lid is also an important feature they should have. Having to worry about spilling in my car, at work on in my lunch bag is annoying. I feel these would be great additions for them and may help keep things hot longer. Overall, I will continue to use my Yeti as it was a pricey purchase, however I will not be purchasing any further mugs.

Rated 5 out of 5 by from Hot stays hot, cold stays cold. Got the 20oz tumbler for Christmas, was amazed that when filled with hot coffee, the coffee was still hot hours later. No heat transfer thru the sidewall. We are in Canmore Alberta, and when my Yeti was placed n the -15C cupholder in my Grand Cherokee that was parked outside overnight, the coffee stayed too hot to drink all the way to Calgary! That is a one hour drive! Finally had my last sip of hot coffee as I finished it off about 3 hrs later. Used it as a cocktail tumbler, left over ice was still ice the next morning. Amazing!
