YETIRambler Vacuum Insulated Tumbler with Lid

OMG, Summer lifesaver on the golf course!

A lot of comments on focus on cold beverages but do not really touch much on the hot beverage side of things. Insulation tends to retain temperature, whether hot or cold. So with this in mind I mixed it up with the 30oz yeti and done both hot and cold beverages at random points in the day over a 2 week span to test how long it would last, and if different types of drinks lasted longer than others.I first tested my favorite, wild cherry pepsi. I am no ice man and usually stay away from this because of it's ability to quickly melt and water down any drink but for the purposes of this test I added three small cubs to the cup and closed it, sat it on the table in the living room over night (the heat was on 70 in our home) and checked it in the morning. It stayed out for about 6 or so hours and some of the nice had melted but not all of it, which surprised me! I didn't expect all of the ice to melt but I did assume that it would eventually have to melt a little, which it did, but it didn't melt entirely. The second thing to note and what many comments haven't really mentioned is the taste of the drinks. Most carbonated drinks will go flat fairly quickly when left out, even quicker when you add in melting ice. This was not the case and this is what I seem to love most about this yeti. My Pepsi tasted just like I had opened a can of it and started drinking it fresh. There was still plenty of carbonation and fizz and it really hit the spot.I tested this the next few days on other things like chocolate milk, iced water and iced coffee, all with the same results as the Pepsi the first night. I decided at this point to kick it up a notch and I took this to a sauna with me. Adding extra heat and moisture cut the time down by a little for the ice to melt but the drink stayed cold and delicious through the day.I decided to test coffee one morning before I headed to work. I added in the coffee and left for the day, it was 8am. I was able to drink this until it was gone at 3pm and it was still very warm. Seems to work with both hot and cold drinks.

Yeti 30 oz tumblers are my husbands favorite. We have had 2 for over 10 yrs. Just ordered 2 more.

Just like everyone else says, this thing keeps your drinks both hot and cold for hours! Wanted to buy them and saw they were on sale, JUST the stainless color for 25% off on the YETI website, checked Amazon and saw they were selling for the same price so obviously I bought them on here so I could use 2 day shipping. Mine is definitely authentic, mine was ordered from Pronghorn Outfitters or something like that. I googled for hours after it arrived to be sure it's authentic and everything I checked proved it is.I didn't leave a hot beverage in mine long enough to actually test out the length of time it kept my drink hot, but I'm more of a cold drinker anyhow. Both my husband and I purchased these, he got this one and I got the 20 oz and we sipped from them and refilled them all day long. The drinks stayed ice cold! My husband even left ice in his overnight and didn't even think about it, we intended to purposefully do that but he just so happened to leave some! When he got up the next morning the ice was mostly still there, just a little bit melted!I have a few complaints but they don't really make or break it for me. For one, I hate that the bottom is stainless steel. I feel like it will get scratched easily, though not a huge deal but I'm anal about my things looking nice, I don't like my things to get scratched and beat up. It also seems like it would be less likely to slip or tip over if it had a rubber bottom or something to that effect. I also don't love the lid. I haven't really traveled much with mine yet, but I feel Iike if you had a full cup and was driving on a bumpy road you would surely get splashing and spillage in your car. The mouth is left wide open. (I do see they are making a lid that closes and it's not available until next month but people have been apparently buying them from a brick and mortar outdoor store and the reviews aren't great at all. Not sure if they are buying actual YETI brand lids or if they are getting knockoffs so we'll have to wait and see I guess.)I also wish they made these in more colors, they do make a couple but since the stainless was on sale I went with that and plan on personalizing them with my Cricut vinyl machine. I would love more girly colors though like pink or purple. I've seen some online but not sure if they are knockoffs or legit so I didn't bother.

Great

Excellent quality tumbler and an awesome vendor! Thank you!
