In total I had 6 of their double wall vacuum insulated thermoses, ranging in size from the 10oz Tumbler up to the 32oz Tumbler. 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. The Ozark Trail tumbler won our second ice retention challenge, this time but a wider margin. It held ice in brutal Alabama August heat for 12 hours and 42 minutes. One reason the Ozark Trail tumbler held ice so much longer may be due to the fact that the sun was so low in the sky.
The Orca has drained 15 ounces and the Ozark Trail 14 ounces. 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. It features a double wall vacuum seal design and is built from high-grade 18/8 stainless steel.
It is hand-wash, but I ozark trail chair did wash the lid with no problems. There are a few key features that are really important to me and created a good benchmark of which brands to include. They had to be insulated for maximum chill factor (no one likes a warm drink), include a straw or a lid with room to add your own, fit in a cup holder, and be a large size. I did my best to keep the sizes comparable across brands, so each one has a capacity between 24 to 40 ounces.
Even though both claim to be leak-proof tumblers, I held both upside down and they both leaked a lot! Because of the handle, for example, you won’t be able to put them into the side pockets of a backpack either. The design is very sleek with a thicker top and narrow bottom. The flexible straw is very convenient, but it is hand wash only. If you prefer the subtly etched ozark trail chair silver look to black marking on the silver tumblers, we offer sand blasting! You are able to purchase additional lids both in a spill proof configuration and the open mouth version that comes with the tumblers.
There are many different sizes and colors to choose from. You will need to buy your own straw since one is not included or just sip from the cap. When you close the lid, it is a pretty secure close but there is still a little leakage. It would be a great tumbler for kids or high schoolers since it comes at such a great price.
