If you love drinking through a straw, the Klean Kanteen Insulated is the tumbler for you. While many tumblers offer a straw lid option, this one is our favorite both to use and to clean. The stainless steel straw turns to bendy silicone just above the lid, allowing you to handily bend it to drink, just like your favorite childhood plastic version. Around the base of the straw, a silicone seal does an astonishingly good job of preventing nearly all spills — we had to slosh it vigorously at a 90-degree angle to get even the smallest drop to squeeze through. That silicone seal also pops out for easy cleaning but remains attached, so you won't lose it. In addition to keeping hot drinks warm and cold drinks chilled, insulated mugs are also designed to prevent spills. Some have sippable snap-seal lids, while others come with reusable straws made of plastic, rubber or metal.

This good-looking tumbler features great insulation, a full seal for tossing in your bag, and easy one-handed opening For one thing, the Beast is sometimes cheaper than the Yeti. While this is not necessarily a bad thing, you might find that a Beast tumbler won't last as long because the quality is just not the same. 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.How easy it was to clean each tumbler: We washed each tumbler according to the manufacturer's instruction and noted how difficult or easy it was—as well as whether any special tools like bottle brushes were required. After testing, the tumblers with stronger beverages like coffee, we noted if there were any lingering aromas. 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. We spent a month using the best insulated tumblers side by side with water bottles and travel mugs. We found that the RTIC – 30 Ounce Tumbler gives you all the same insulation performance and better leak-proofing at less than half the price of the best-known YETI – Rambler. If you’re willing to pay, YETI does give you a slide-open spout that’s less annoying, though you run the risk of dribbles and drips. Table of contents If you are looking for a tumbler in which you can make a hot cup of coffee then simply throw it in your bag, there is a chance you could have a big spill to clean up. This is not a leak-proof lid and is simply ‘spill-proof’ which is important to know. 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.

Spout stoppers: Flip-up stoppers and slide-over stoppers are the two common approaches to keeping a tumbler closed. Look closely at what you’re buying, though: Many tumblers are made with a few different lid styles if you look for them. How the materials affected a beverage's taste: We tried different beverages to see if the tumblers' materials affect taste, including plain water, juice, smoothies, and coffee. The Hydro Flask – 32 Ounce Insulated Tumbler is a notable contender from one of the big names in the world of insulated drinkware. Many publications give it a win for the sleek profile and brand reputation. This piece was updated by Derek Rose, the coffee and tea expert for The Spruce Eats. He researches a variety of coffee products, from measuring scoops to commercial espresso machines, and interviews field experts for their insight. Painted, coated or brushed finish: Color coordination is a nice benefit of painted or powder-coated tumblers, but they’ll show signs of wear eventually. Brushed stainless steel looks great even if it gets scratched, and there’s nothing that will peel off after a few years. How we tested Everyday use tests

While the body of the mug is a bit hard to hold because of its sleekness, the handle is lined with cork, which our tester likes because it provides cushioning for your hand. Plus, the lid is leak-proof and has an easy-to-use slider. There are a few design details that could be improved, however: For example, the mug may not fit in most car cupholders due to its handle. Note: The 32oz model we tested has been sold out since July, so we’ve updated all links to point to the 22 oz model of the same design. Renu Dhar, a personal chef, culinary instructor, and food blogger, tested the popular Stanley Quencher H2.0 FlowState Tumbler on multiple errands, road trips, and everyday journeys from her desk to the gym to her car. The lid is advertised as, “Sliding Spill-Resistant, Shatterproof Crystal Clear Straw Friendly BPA Free”… what a mouthful!

Stainless steel is the standard for insulated mugs since it’s easy to clean, doesn’t cling to odors, and has fantastic temperature control compared to other materials like plastic. 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. In our water bottle review and travel mug review, we’ve seen Klean Kanteen and Hydro Flask go head-to-head competing for a position in our tests. For the first time, Hydro Flask offers something substantially different from Klean Kanteen: a bigger cup that actually matches what everyone else is offering. Vacuum-insulated tumblers or bottles feature a double wall, or two-layer construction—oftentimes made of stainless steel,” says Graham Nearn, Stanley’s Vice President of Product Creation and Design. “All air is removed from between the two layers of the bottle to create a vacuum.” This feature is why this kind of tumbler is able to keep beverages at the preferred temperature for an extended period of time. Beast tumblers come from the company known as Greens Steel. Greens Steel is a bit newer than Yeti Coolers, having been officially started in 2015. Greens Steel was created out of awareness for the damage that single-use plastic has done to the earth. This goal is reflected in their name, Greens Steel, and the company focuses on making tumblers and other drinkware that is completely eco-friendly.The world of insulated tumblers is overwhelming. There are more options than ever, and each one seems to boast some game-changing technology or eye-catching feature. But when it comes down to the basics, what you really need is something that will keep your cold drinks cold, hot drinks hot, prevent spilling, hold up to the bumps and bruises of life, and look pretty good doing so. With those criteria in mind, we went on a journey of finding the very best options you can buy.
