With their tapered, narrower bases and uncapped straws, they’re bound to be tip- and leak-prone. However, this doesn’t mean water should flood from them when tilted. It had excellent cold retention, didn’t leak, is available in a plethora of colors, and is reasonably priced. The Stanley The Quencher H2.O Flowstate Tumber did well in our tests, too, for those wondering whether it’s worthwhile investing in the viral item. All in all, both mugs do an incredible job at insulating both hot and cold drinks for hours on end. What is more, this product is also surprisingly easy to clean – even though it’s dishwasher-safe, I just rinse it out by hand. Neither the Ozark Trail nor the Yeti are designed to be leak proof, unlike insulated stainless steel water bottles. As a trail tumbler, it is important to consider what kind of travel is best.
