Like many other tumblers on this list, the Maars Bev Stemless Wine Glass Tumbler is constructed of 18/8 stainless steel with double-walled vacuum insulation. Unlike many other tumblers on this list, the Maars tumbler is explicitly designed with wine enthusiasts in mind. (Just because it's a wine glass tumbler doesn't mean you only have to drink wine in it—we envision this being good for any setting where a smaller tumbler is preferred.) The Yeti tumbler lid comes with plastic o-rings that secure the lid to the tumbler itself. Unfortunately, sometimes these rings can slide off or be pulled off of the lid over time with excessive use. The Beast: Pros, Cons, and the Origins When they say double insulated, they aren't kidding. You will find that any ice you put in your Yeti tumbler will last for an entire day, if not longer. Conversely, any hot drinks that you choose to put in your tumbler will remain hot until the last drop is gone. This says a lot about Yeti's reliability.

So, the ideal setting for an insulated tumbler is on a hot afternoon where you want to keep your drink insulated, but you’re more worried about convenience more than spills. Drinking something cold poolside on a scorching-hot day is a perfect example. Reading on the patio in the early morning with a cup of coffee is also a case where the tumbler works better than an ordinary cup. The bottom line Without buying and trying out these tumblers, it’s easy to make assumptions about performance. “Maybe the steel is thinner,” you think. “Maybe the vacuum is actually less of a vacuum.” Our testing shows, though, that If there’s anything fancy that other brands are doing to improve theoretical insulation performance, the giant plastic lid is an equalizer that levels the playing field.This is a rare, yet very special feature we totally love! 3. Comes With x2 Premium Unbreakable, Rust & Scratch-Proof Stainless Steel Straws If you're tired of bringing a fresh iced coffee to work only to find it watered down too soon thanks to the summer's heat, then an insulated tumbler might be exactly what you need. Because of their construction, which consists of double walls and a vacuum seal, these tumblers are perfect for when you’re on the go and want to keep your beverage hot or ice cold for hours. It comes in a wide range of appealing colors and in a beautifully presented gift box that is completely recyclable. During testing, this tumbler didn't leak at all. It also performed very well when it came to cold drinks, with under-40-degree temps lasting for over 10 hours. A tumbler’s insulation should not deteriorate with prolonged use. “However if any insulated tumbler is damaged, thermals may be impacted,” states Nearn.

The Yeti's design is another upside of owning one of these tumblers. The walls are double-vacuum insulated and the tumbler has a mag-slider lid, which is extremely easy to remove and wash. With its 18/8 kitchen-grade stainless steel construction and no sweat design, it is not only a durable tumbler to use, but a convenient and comfortable option as well. It is also incredibly easy to wash, thanks to its easily removable mag-slider lid. These mugs are safe for the microwave if you need to heat or reheat a beverage, as well as the freezer, so you can, for example, freeze portions of fruit in each glass. Unlike some insulated glasses, they can be washed in the dishwasher, so cleaning is easy when the party is over. We love the flat siding, as it makes it way easier to grip, especially when by the pool or grill. This cup also comes with a spill-resistant lid that features a slide closure and a removable silicone gasket to make cleaning easier. Per the manufacturer’s recommendations, this wine cup must be hand-washed.Of the two brands that are trying sliders, YETI is fairly successful, while Pelican’s lid is a hot mess. It’s not clear exactly what the issue is, since the basics of the mechanism seem the same, but the Pelican lid always dribbled a stream of water when we turned it upside down. The YETI “Mag Slider” lid isn’t as magical as it sounds, but it works fairly well to stop anything more than occasional drips. Size: During the testing period, we placed the tumblers in bags and standard cupholders to asses their size. We also noted the maximum capacity and dimensions of the tumblers. So, what is the difference that brings the price down? The plastic “foot” on this new RTIC is less tough than the YETI if you drop it on a hard surface, but the difference in price more than makes up for that. On the cleaning instructions provided by Greens Steel, there is a note stating you need to leave the lid slider open for 1-2 minutes before closing to prevent this from happening. Pelican is a company that makes quality flight cases for sensitive equipment, and in many ways they’re like YETI: a small company who established a niche with a specific product, then started building a brand around it. This tumbler is a bit different than the rest, and if you love the screw-on lid with the bigger spout area it’s a good buy.

Now that you know some pros and cons, let's talk about what Beast and Yeti tumblers have in common. For starters, the pricing is typically the same; Yeti and Beast tumblers have a variety of sizes ranging up to 32 ounces.Vacuum-insulated cups, which are typically made of metal or glass, have both an inner and outer wall that is separated by a thin layer of vacuum. The outer walls have a reflective coating to keep heat inside the inner chambers; meanwhile, convention (how heat rises and cold sinks — causing the loss of heat) is prevented by the cup’s lid. Between the various well-known brands that are just barely different from YETI, RTIC is budget-friendly and offers a flip-cap lid that at least compares in functionality to the Mag-Slide on the new YETI lids. The one category YETI manages to squeak ahead of some competition is in spill prevention. The Rambler’s slide cover actually stops most (but not all) leakage and only lets drops escape. In comparison, the Pelican will dribble out a stream. The RTIC is more leak-proof, but the YETI really is ready for those times when your friend fires up the motor on the jet boat and you haven’t finished your drink.
