We have read through this guide and insisted on our choice.
Leaving 16 thermos cups full of Slurpee behind the front seat of a hot car, we are sure that the Hydro Flask 22-ounce tumbler is the best choice for most people. Even with a high temperature of 112 degrees, we found that most of the insulation values between the glasses are effective (they can keep your drink hot or cold for several hours). The performance and aesthetics of Hydro Flask make it a winner.
This slim powder-coated tumbler fits easily in hands and cup holders, which is why we like it.
Our favorite tumbler is the 22 oz Hydro Flask. Unlike a water bottle or thermos, a tumbler cannot be thrown into a bag. It only keeps the heat and cold when you need to get from one place to another, and allows you to sip easily during the journey: it is the ultimate commuter boat.
In our refrigerated Slurpee test, five glasses stood out, and Hydro Flask ranked in the top five. It ranks second in our heat retention test, with only one degree difference in temperature, so it can easily maintain the temperature of your coffee during your commute. But aesthetics is the reason people like this thing. We chatted with a dozen people (or more) while having dinner by the campfire, and they all thought that the Hydro Flask was easier to hold and more enjoyable than any of the other 16 models we’ve seen — —This is really important for tumbler lovers. Hydro Flask has the thinnest and most coveted shape of all glasses we have seen, and has eight delightful powder coatings. We prefer those to ordinary stainless steel glasses because they will feel hot to the touch if they are placed in the sun.
Hydro Flask offers lids with integrated straws for the 32-ounce and 22-ounce versions of the tumbler. We have tried it on a larger version and it is great: safe, easy to disassemble and clean, and equipped with a flexible silicone mouthpiece to prevent soft palate tingling.
Finally, we emailed the company to ask if it can be cleaned in the dishwasher. Reply: "Although the dishwasher will not affect the insulation performance of the flask, high temperature and some detergents may discolor the powder coating. Similarly, immersing the entire flask in hot water will discolor the powder coating."
Basically the same as our first choice, except for a slightly wider taper (which feels more like pint glass) and a more gripping colored coating.

From insulation performance to minimalist aesthetics, Klean Kanteen is almost the same as our first choice in every aspect. In our cold test, it was in the same group of finalists as Hydro Flask, although it did not perform well in terms of insulation. After 2½ hours, the coffee temperature is 139 °F, which is 13 degrees lower than Hydro Flask. We think this is enough to make it a runner-up, but it is still a good choice because according to the National Coffee Association, 140°F is still comfortable to drink).
Shape wise, it is more like a pint glass, if you get any of the three colors of glass, the coating feels more tactile, just like it is coated with rubber. It is 2 ounces smaller than the Hydro Flask and does not have an insulating cover, which may be the reason why it cannot hold heat (just guessing-there are too many things that affect performance and we can't make calls).
It comes with a standard coffee sipping lid, but Klean Kanteen's straw lid also has a glass and straw set. Again, the design is almost the same as the Hydro Flask: the metal straw is equipped with a curved silicone nozzle. Only the cleaning portal is slightly different.
The wider shape makes the snowman feel at home in the farm, construction site or camp.
Like the image of Yeti, the Yeti Rambler 20-ounce tumbler feels very practical because it has a wider body shape than our preferred product. Since most of the reasons that make one tumbler more popular than the other have to do with how it feels on the hand, we think it’s worth recommending to those who won’t get caught to death (there are a few at our campfire dinner)-than 100% burly drinking fountain.
In terms of performance, it is comparable to our preferred product: it ranks among the top five in terms of cold retention, and can keep coffee hot for 2.5 hours at 144°F-a few degrees below our defined warmth value, but still very good good.
The Rambler used to have a standard lid—you can actually put a straw through it—just like all other glasses. However, now it is equipped with a MagSlider lid, which can be neatly closed and has a straw port (although it is not leak-proof). If you really want a standard lid, you can buy it separately, there is also a dedicated straw lid, and even a cup handle to help carry (this is a small piece of evidence for us to prove the slim shape of the Hydro Flask Does make it better for most hands).

You might ask, "Why do I need a tumbler?" Well, when we talked to readers, we found that obviously people have infinite curiosity about things that carry drinks. In the past year, we have provided guides about water bottles, water bags, wine glasses, coffee cups, etc., but we still receive information about tumblers (hence this guide) and growlers (beer cans; we also have guides) Such problems. We don’t want to go further on this wet road and enter lesser-known containers — no goatskin botas or mate gourds (we hope) — but there are multiple ways to avoid landfill clogging once The idea of sex bottles and cups is what we like. We hope you do the same.
While we are conducting original research, we are trying to understand every new glass that was launched in early 2018. At the outdoor trade show for outdoor retailers in the summer of 2017, we stopped in front of each booth where the glass was displayed and listened to the designer's in-depth introduction, focusing on the uniqueness of each booth. Since then, we will return to OR's summer market every year to monitor the development of the tumbler field (and other fields).
Usually Internet research is the first step when we start testing products, but for this guide, we are lucky to be able to conduct the research ourselves. We walked through the floor of the outdoor retailer's summer market trade show. This is an annual event where hundreds of brands showcased their latest innovations and selected each glass on display, 18 in total.
We talked to every designer and manufacturer and asked a lot of questions: Does it fit the cup holder? Is there a splash guard or straw on the lid? Is the drum dishwasher safe? What is it made of? How is the quality of success? How many color options are there? How many sizes are there to choose? Is there a non-slip traction on the bottom? As a single container, can it meet the needs of the whole day: sunrise coffee, morning smoothie, lunch ice water, afternoon lemonade with ice, sunset beer, evening cocktail, supper tea?
Lid design may be the biggest differentiating factor. The standard has a medium-sized opening on one side of the mouthpiece, designed to restrict the flow of hot drinks, but allow cold drinks to flow. Some brands have additional accessory covers, such as sliding, rotating or flipping lids for openings, which will have a splash-proof effect but not leak-proof.
The best choice for tops is the one-piece one-piece lid, which can be completely closed and can accommodate a straw. Straws are necessary for iced drinks or smoothies to prevent shaking. The last factor in lid design is cleanability. Sticky things such as coffee milk are easy to get stuck in the gap. Most brands take this into consideration, but small individual parts may not be easy to disassemble and reassemble (and may have a tendency to disappear).
However, we found that the most technically practical lid design is not important for ordinary people who desire hydration. We spent the entire evening around the bonfire with about 100 industry designers and professionals, and asked 100 questions about their tumbler of choice. The only thing that really matters to most people is the feel. (There is also a lot of brand loyalty; people tend to find their favorites and stick to them.)
We conducted two tests to understand the effectiveness of these beverages to keep them hot and cold. The packaging likes to emphasize that this can make the drink "four times colder" or "cooler". But four times colder than what? At what temperature is longer? In addition, they all have different capacities. We chose containers of similar size, but there are still slight differences that affect heat preservation and cold preservation. We came to the conclusion that trying to test these in a super-scientific way is not very practical.
Since the tumbler is the ultimate vehicle for transportation, whether it is commuting or road trips, we concluded that it is enough to keep a hot car for 3 hours and a cold car for 4 hours. This may not sound like much time, but it allows you to brew your morning coffee, pour it into a cup, sip it while you are dressed, get you into traffic and arrive at the office while the cup is still piping hot. This also allows you to make a smoothie, go to the gym, and still have a cold refreshing drink when you are done.
We drove the fast-heating black car into the parking lot in front of the 7-11 convenience store in the heart of Salt Lake City. The outdoor thermometer reads 92 °F—this is the typical temperature in the midsummer high deserts of Utah. Since the nearest puddle is slightly beyond the scope of rapid launching, we chose a tried-and-tested American classic-7-11 Slurpee. Conveniently, we have 15 vacuum flasks to fill up.
Our control Slurpee in a standard 7-11 plastic cup lasted about an hour, while the insulated counterpart continued to maintain about 50% of the original density during the third hour.
We filled them with ice and snow truffles at 26.3 °F and covered them with lids and straws.
All 15 people sat in the front seat of a black car on the roof of the downtown parking lot, where the internal temperature reached a maximum of 112 °F. We check the progress of the melting every hour without opening the lid to confirm that there is still some slush in the glass. If Slurpee becomes pure liquid, its cup is broken.
Our control Slurpee in a standard 7-11 plastic cup lasted about an hour, while the insulated counterpart continued to maintain about 50% of the original density during the third hour. By the fourth hour, Corksicle was the first to completely liquefy its contents, and Coleman was almost there. At 5 hours, Reduce, Mizu and EcoVessel contained liquid.
The infamous "Beware of the heat!" McDonald's serves coffee at a temperature between 195 and 205 degrees Fahrenheit. According to the National Coffee Association, this is the right temperature for brewing coffee. They said: "Your coffee machine should keep the water temperature between 195-205 degrees Fahrenheit for the best extraction effect," they said, but this is too hot to drink: "Before enjoying coffee or any hot drink, Make sure it reaches a comfortable temperature (especially below 140 degrees Fahrenheit)."
We started below the brewing temperature and filled each glass with 180 degree hot coffee (without creamer). Every 30 minutes for 3 hours, we use a digital probe thermometer to measure the internal temperature. There is an outstanding (Ecoflask), a group of ultimate competitors, and a product area. In most cases, everything is fine. The coffee in our cup was cold in 20 minutes.
The EcoVessel 16 oz tumbler is excellent in every aspect, from insulating properties to maintaining ergonomics and sealing the lid, but we think it is too small. The company has since introduced larger sizes, but—in Goldilocks’ twist—the new version has 24 ounces and is too big.
Pelican Travel Tumbler: The best insulation performance, and we really like the splash guard on this lid. It is just a very large ship, too strong for most people (for example, much stronger than a snowman). If you are a big person who likes big things (Pelican even talked to us about this topic), this is your tumbler.
Otterbox Elevation 20: Although it is only 20 ounces, it feels heavy in the hand.
Thermos Stainless Steel King: Although they call it a tumbler, we think it is more like a container for hot drinks only. Although there are some more stylish models with novel 360-degree lids—an interesting solution that allows you to sip from anywhere—but its limitation is that you can’t put a straw into a smoothie or iced drink.
Reduce cold vacuum tumbler: The lid feels very fussy, and the mouthpiece and straw hole have been flipped many times.
Zoku 3-in-1 Tumbler: Our testers were indeed mellow by this tumbler-maybe sexy? ——The influence of shape. This may seem too dramatic, but unlike other straighter designs, our testers tend to put Zoku aside.
Coleman Brew Insulated Steel Tumbler: We really like this design because it fits well in the hand and has a rare non-slip bottom. But it performed poorly in insulation tests.
Camelbak Kickbak Tumbler: The hot and cold retention is very good, but Camelbak's double-sided flip cover is polarized. This design solves various problems-splashing water, ingress of straws-but some testers say they hate flipping the lid. (The size we tested was 20 ounces. Since then, production has been discontinued, and the larger 30 ounce size is being cleared.)
Mizu Tumbler: Only available in stainless steel or black uncoated metal, this model is at the low end of our insulation test.
Corksicle: One of the few cups with a non-slip bottom. It also has some other excellent design elements, including a splash cover, an ergonomic grip, and approximately 1 billion colors to choose from. Performed at the lower end of the insulation test.

Experts agree that it is good to drink water. But if you have trouble forming a habit, maybe you need to reconsider what you drink.
All-inclusive resorts don’t include everything, so Wirecutter’s travel staff picked what you really need to relax.
At Wirecutter, we love tea and coffee, so it's no surprise that we are passionate about the containers in which we drink them. This is the cup we can't buy enough.
Authors: Michael Sullivan and Eve O'Neill
After more than 60 hours of research and testing, and many dropped glasses, we believe that the durable Bormioli Rocco Rock Bar is the best multi-purpose drinking glass.
