My goal was to see how long I could keep a cup of coffee warm and if there would be variation in temperatures over time across the tumblers. I also used two of the 22oz Tumblers, one with the standard open mouth lid and one with a closed, spill proof lid. Double-wall insulated tumblers are all the rage and for good reason! They can keep drinks cold or hot for hours, which can truly be a lifesaver whether you’re on the road, in the car, at the office, or at home. If that doesn't bother you, this plain-Jane insulated lowball will keep your campground cocktails chilled at less than half the price of the fancy Yeti version. If you absolutely must have colored tumblers, Ozark Trail sells a four-pack of 12-ounce lowballs for about $35. Thirty ounces of your favorite hot or cold beverage will keep you hydrated and happy. Their signature MagLock sliding cover on the lid is a cinch to use, owners say, but even some people who leave five-star reviews admit it's not 100% leakproof 100% of the time. This cooler has a number of features that you would find on more expensive coolers and a few that you won’t find. Obviously, the performance of this significantly more affordable travel mug is not as good as that of its rival. While Ozark Trail 12 oz mug does feature double-walled vacuum insulation, it is not capable of maintaining the temperature of the beverage for a very long time. Other great things are that they both fit in drink holders and are easy to grip without condensation. It seems to be the same quality tumbler as more expensive competitors; you just aren’t paying for the Ozark Trail, Yeti or RTIC name. A petite person or child may find the 30 ounce size to be a bit of a challenge to use. There is a notch to stop the straw from coming out of the drink but it doesn’t make it leak proof. They are made with food-grade 18/80 stainless steel and are BPA-free. This mug comes in one color which is silver, so if you like the tough industrial look of steel, you will love this mug. When purchasing from Walmart’s website, you have the option of selecting one of 4 colors; black, mint, silver, or tan. Another great thing that Walmart provides is the ability to purchase the 32oz Ozark Trail Tumbler in quantities of 1, 2, 4, or 6. I’ll be totally honest, I was not expecting this cooler to be as nice as it was. It’s easy to get caught up in brand perception and often times very difficult to break away from what you think you know about a brand. I used the word “think” intentionally, because what I thought I knew about Ozark Trail was not correct. Ozark Trail is proving to be a really solid competitor for outdoor products. Tumblers enable office workers to enjoy their beverages hot and cold. Unfortunately, like most all water bottles and tumblers, they are made in China. Ozark Trail tumblers are not dishwasher safe thus you will have to clean it the traditional way which is by hand washing. This brand is made with the same type of 18/8 food grade stainless steel as the Yeti, RTIC tumbler and Ozark Trail. With a price point below $10, you are able to get 4 of the 32oz Ozark Trail Tumblers for a price that is comparable to 1 of the competitions 30oz tumblers, which to me is a huge win. Yet if you have a regular glass in the office, chances are you won’t be able to enjoy one after coming back from an hour long meeting. In fact, when you place the Ozark and the Yeti tumblers next to each other, you would have a hard time figuring out the differences. You can basically get the same type of performance that Yeti Tumbler can give you but get two of them for the same price. It is very much capable of keeping your coffee and tea hot for an extended period. Look how cute these Ozark Trail 18 oz Insulated Stainless Steel Tumbler with Handle are for just $9.98! With a 40-ounce capacity, this reusable tumbler is the drinkware everyone needs in their pantry. Double wall insulation and double wall lid keeps liquid hot and cold longer. A handled coffee mug just gives the feel of sitting back and relaxing as you get ready for your day.
