All in all, both mugs do an incredible job at insulating both hot and cold drinks for hours on end. Additionally, when holding each tumbler, I couldn’t feel any heat or chill through the material, which makes either ideal for drinking exceptionally hot or cold drinks. You might have to wait closer to an hour for your hot drink to actually be drinkable (around 135°F). The water in the Yeti tumbler did cool down slightly slower than the Ozark Trail one, but not enough to cause a significant difference in experience between the two.
Many outdoorsmen have taken their infield coffee preparation to the next level making pour overs or using a coffee press. If you plan to do something that is more in line with a high end coffee shop, you should consider this Tumbler. To help me understand what the Ozark Trail Thermos line from Walmart could do, I assembled a collection of sizes that I picked up in person at my local Walmart. In total I had 6 of their double wall vacuum insulated thermoses, ranging in size from the 10oz Tumbler up to the 32oz Tumbler. Like most things in life, there is so much more that goes in to your coffee than flipping on your coffee machine. To achieve the optimal cup of coffee you have both a recommended brew temperature as well as a recommended serving temperature.
This allows hot drinks to stay hot and cold drinks to stay cold, and it’s “MagSlider Lid” helps prevent heat or cold from escaping but won’t entirely prevent spillage. It’s claims to be BPA-free and has a “no sweat” design, which keeps fingers dry. As an avid outdoorsman, I can say from experience that a hot ozark trail chair drink on a cold morning or a cold drink in the blazing heat of a midsummer day is a creature comfort that I can’t live without.
Using a thermal imaging scope from ATN, I filled one of the 22oz mugs with water boiled to 185 degrees Fahrenheit and another filled with water boiled to 140 degrees Fahrenheit.

One of the main reasons that you are filling a thermos is to enjoy your beverage at the desired temperature over extended periods of time. To that end, you may be out and about for hours which means having more of your favorite drink on hand will be beneficial. If you are wondering what makes a double wall vacuum sealed thermos superior to other designs, we can help clear the air. Not surprisingly, both tumblers were better at maintaining cold temperatures than hot with the cold temperatures rising at a much lower rate. Even though the tumblers had slightly different initial temperatures, it took both cups approximately 45 minutes to raise 1°F.
With the locking lid, there appears to be more heat transference than the open mouth lid. Even with the locking lid absorbing more heat, it does provide a few degrees more heat retention over time. I began with my initial 185 Degrees Fahrenheit temperature and tested each Tumbler 2 hours after placing the water inside, 4 hours after placing the water inside and 12 hours after placing the water inside. I tested the temperature using a Weber meat thermometer which was $15 off the shelf. I used plain water which I boiled to temperature and placed inside each of the Tumblers and immediately closed with the provided lids. If you love espresso or plan to use the Tumbler for a cold beverage, the 10oz Ozark Trail Tumbler is going to be a great option for you.
After extensively reviewing the data from the travel logger, we found that—drumroll, please—the two tumblers performed exactly the same. I’ll pause for shock value, but there’s no real difference between the two other than the price tag and that the Yeti is dishwasher safe. 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.
The locking lid and open mouth lids do seem to provide similar results when paired with the 22oz Tumbler, but I had one more text I wanted to run. I won’t go crazy with scientific research in this article, but I will reference just a single study to provide some context. To take this a ozark trail table step further, you may encounter a noticeable change in flavor as your coffee’s temperature reduces.
