The only real physical differences are that Yeti has a slider on the lid and they have different logos adorning the cups (obviously). 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. Well, I’m here to quench your thirst for knowledge by doing a deep dive into both the Ozark Trail and Stanley Cup tumblers. Now, to be more competitive with Yeti, they have a wide range of colors and styles. Tumblers enable office workers to enjoy their beverages hot and cold. According to The Wall St. Journal, in terms of maintenance, Yeti Tumblers seem to have an upper hand over its competition as the Yeti is dishwasher safe. A petite person or child may find the 30 ounce size to be a bit of a challenge to use. The only complaint I might have is that in the 30 ounce size, both are a bit difficult to grip if you have small hands. I love being able to use the dishwasher to be sure it’s clean and for the convenience. One difference I noticed is that the YETI brand specifically states dishwasher safe and Ozark Trail says to NOT place in the dishwasher. However, we have personally washed the Ozark brand water bottles and tumblers in the dishwasher at my house without issue for years. Double-wall insulated tumblers are all the rage and for good reason! They can keep drinks cold or hot for hours, which can truly be a lifesaver whether you’re on the road, in the car, at the office, or at home. The insulated tumblers either had twist-on or press-in lids. Neither was better or more secure (both styles had winners that leaked and others that didn’t), so it’s a matter of preference.
