The proprietary Permafrost insulation of this Yeti cooler, on the other hand, helps with ice retention, while the Fatwall (another proprietary technology) design provides 2” of ice insulation. During drop-testing, Yeti Rambler 26 oz ended up with only a couple of dents on the bottom of its body. In other words, this is a very sturdy and well-made hiking water bottle, and I’ve expected nothing less from Yeti. The final feature of this phenomenal bottle is its wide mouth – it makes cleaning easy and allows you to throw as much ice into it as you want. This is what makes Yeti different from many other insulated tumblers. Unless you really care about being able to wash your stainless steel tumbler in the dishwasher, the Ozark Trail tumbler is a more practical option than the Yeti tumbler. Double wall insulation and double wall lid keeps liquid hot and cold longer compared to previous tumbler. Both have a 40-ounce capacity paired with a smaller base that fits into most cup holders. Plus both options are made of vacuum-insulated stainless steel for optimum temperature regulation. They’re both designed to be dishwasher-safe, BPA-free, and have a lifetime warranty. When it comes to premium coolers, travel mugs, and insulated tumblers, Austin-based Yeti is probably the most well-known name in the game. Ozark Trail, on the other hand, is a Walmart-owned brand under which the company sells similar products, although at much lower prices. In other words, the ice is held closer together and not allowed to spread out. As the ice melted in each tumbler, the water was poured into a measuring cup at roughly 8-hour intervals. 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. For those with dexterity or hand strength concerns, the press-in lids were easier to add and remove. The Yeti and MiiR in particular had sizeable plastic tabs on their lids, which you can press your thumb upwards on and use to pop the lid off (though the Yeti requires more force). This Stanley tumbler’s lid is much improved upon compared to the previous iteration. Its silicone seal stopped water from flooding out (though it’s not leakproof). The silicone portions on its handle were exceptionally nice to hold, too. They aren’t porous like plastic tumblers so they won’t stain or retain odors. We love using a straw to drink from, especially while driving. They are made with food-grade 18/80 stainless steel and are BPA-free. Therefore, a cup that is sturdy, reliable, warm, cold and easy to carry is very important. ©2024 Reviewed, a division of Gannett Satellite Information Network LLC.
