Walmart’s answer to Yeti’s popular product is a bottle that has many similarities with the aforementioned model – it also features an easy-to-carry handle and an overall sweat-free design. In addition, it is made out of BPA-free materials and comes with double-walled insulation whose job is to maintain the temperature of one’s drinks. Obviously, the best thing about bottles made by Yeti is their superior thermoregulatory capabilities, and this model is no exception. The dual-vacuum technology and the 18/8 stainless ozark trail chair steel construction of this bottle work together to keep the cold beverages cold and the hot beverages hot.
But the problem I have always encountered is that in the hot summer, the ice cubes in the cold drink quickly dissolve while in the cold winter, the hot coffee quickly cools off. This leads to a short time to enjoy the drink or have no way but endure an unfavorable experience. Watching ice melt was probably the most difficult task of the tests I performed—only because it seemed to take forever for the ice to melt in each tumbler. I started the test first thing when I got to the office and was waiting for hours on end. By the time I left the office about eight hours later, the ice still wasn’t entirely melted and the water levels in both tumblers seemed to be at the same level.
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. 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.
You can see in the image below that the thermos on the left has the hotter water, however the heat signature on both Tumblers is only present inside the Tumbler. 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. 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.
Hiking refreshes me, my mind, and keeps my body reasonably fit. So far I have walked three Camino routes and many other long distance hikes in the UK, Canada, and around the rest of Europe. You also might want to check out other Yeti coolers, such as the Yeti Soft Cooler or the Yeti Hopper Backflip Cooler. However, I don’t think these Yeti coolers come even close to the Yeti Tundra. I was also impressed by how much ice this premium cooler can hold.
Whichever stainless steel tumbler you choose, you will likely find you carry it with you often. Tumblers enable office workers to enjoy their beverages hot and cold. According to most user reviews, the Yeti Tumbler can keep hot coffee warm for five to six hours at room temperature.
