Whether you are going on a field adventure or driving to work, a favorite drink in the morning is indispensable. But the problem I have always encountered is that in the hot summer, the ice cubes in the cold drink quickly dissolve while in the cold winter, the hot coffee quickly cools off. This leads to a short time to enjoy the drink or have no way but endure an unfavorable experience. All in all, both mugs do an incredible job at insulating both hot and cold drinks for hours on end. It is very much capable of keeping your coffee and tea hot for an extended period. Other great things are that they both fit in drink holders and are easy to grip without condensation. We are committed to finding, researching, and recommending the best products. Crafted from robust 18/8 stainless steel with a sleek powder coating finish, this tumbler stands the test of time, resisting scratches, rust, and the mingling of flavors. Its ergonomic handle promises a comfortable grip, making it an ideal companion for any journey. Engineered to fit most car cup holders, it’s the quintessential accessory for the home, office, gym, or while traveling. You will be happy to know that unlike stainless steel water bottles of the past, these insulated tumblers won’t freeze your hands when you have cold drinks or burn them with your hot beverages. Ten hours into the test and the sun is not straight overhead but hitting the broader surface area on the side of the tumblers. The pavement temperature has fallen to 134.7deg but the external temperature of the tumblers has soared. When you are out on the water, people often sneak over to grab something from the cooler and may not latch it back up. With a hard plastic latch, you run the risk of brushing by the cooler and hitting your shin, which I have done and is awful. One of my favorite features though is the rubber wheels vs. the hard plastic wheels on the Pelican and Yeti. Not only will the rubber allow for a slightly smoother roll when you are pull this cooler along, but it will also be quieter.
