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.

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 ozark trail chair BPA-free and has a “no sweat” design, which keeps fingers dry. As an avid outdoorsman, I can say from experience that a hot 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.
On the other hand, the Ozark Trail tumbler is made of high-grade, double-walled stainless steel and is vacuum-sealed—so pretty much the same as the Yeti. It’s also BPA-free and has a “no sweat” design, but doesn’t have a slider on the lid. Once the lids are placed on to the Tumblers you can see a bit more in relation to how they work.

When purchasing from Walmart’s website, you have the option of selecting one of 4 colors; black, mint, silver, or tan.

To test out the Ozark Trail Thermos line, I used the baseline temperature of 185 degrees Fahrenheit for 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. This design consists of, you guessed it, two stainless steel walls as well as a vacuum sealed chamber that sits in between the two walls. With a traditional single wall thermos, convection occurs transferring the internal heat out or vice versa, impacting the liquids temperature over time and at a greater pace.
In 2013 Missouri was named Best Trails State at the International Trails Symposium, due in part to the increasing popularity of the Ozark Trail. The Yeti is also dishwasher safe, but you should never clean it with bleach or put it in the microwave or freezer. It comes in a few fun colors and there’s also a five year warranty that comes with every Yeti purchase.
