The sun and oppressive heat continues to bake the tumblers eight hours into the test. The pavement temperature rose to 144.8deg, the highest temperature measured all day. The Yeti had an external temperature of 111.5deg, the orca 104.7deg and the Ozark Trail was measured at 122.9deg.
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.
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. 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.
I managed to fit my headlamp, lighter, map, compass, and some tp in the pocket. Because it is cheaper and practically does everything that the Yeti Tumbler does, it is not surprising that Walmart’s Ozark Trail tumblers are selling fast. Owning a Yeti tumbler Rambler is something of a status symbol. 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. Both tumblers look very much the same, so it is a no-contest in this area.
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.
It is rust-resistant and very durable, while its lid deserves special words of praise – it is dishwasher-safe and sports a shatterproof design. After 16 hours the Yeti measured 5 ounces of water drained. The Orca and Ozark Trail were at 4 ounces of water drained.
Nothing came out of the Orca and Ozark Trail and only 2 small drops drained from the Yeti. I started by filling each cup with 15 ice cubes, set them in my kitchen with the lids on, and started the clock. We’re testing the quality between high-end YETI tumblers vs. the very affordable Ozark Trail brand from Walmart. It shouldn’t be cleaned with bleach or put it in the microwave or freezer.
This plain-Jane lowball made by Walmart and sold under the Ozark Trail brand name is actually a pretty good alternative to the model described above. For almost $20 dollars less, you’ll be getting a product that is rust-proof, sweat-free, and well-insulated. Not everybody has the money to buy the most premium hiking water bottle out there. There was one tiny bit of slush that fell apart in my fingers when I picked it up. The Ozark Trail had a bit more ice/slush after draining the water and it remained in the vessel. You are able to purchase additional lids both in a spill proof configuration and the open mouth version that comes with the tumblers.
The model is particularly good at maintaining the temperatures of cold drinks, just as I expected. To test out the Ozark Trail Thermos line, I used the baseline temperature of 185 degrees Fahrenheit for ozark trail canopy all of the products I tested. 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.
