Thermos and Yeti Rambler — how do you choose between the two? Both of these portable tumblers are so similar; are they even different? Well, I found that each has one significant difference that made me lean towards one or the other.
About Thermos
History
The history of the Thermos is unique and interesting. It is a story of a product that has been through so many changes through the years that it can be hard to follow. An original inventor is an unknown man by the name of James Dewar. He discovered that if he placed a container within another container and pumped all the air out between them, it would cause the temperature of the inner container to remain constant for a short period of time.
Outstanding features
Double-wall vacuum insulation
The secret behind Thermos products’ insulation is a double-walled, vacuum-sealed design that doesn’t conduct heat. The air between the two walls is removed in the manufacturing process, leaving only a vacuum that cannot transfer heat from the inside to the outside of the container.
Flexible straw
The Thermos brand has always been known for its distinctive flexible straws, which are built into many of its bottles. These straws make it easy to drink from the bottle without tipping it or unscrewing the lid — just flip it open and drink from the spout. Some people love them, but they’re not necessary if you don’t care about drinking from a straw.
Easy-to-clean lid
The lids on Thermos brand containers are easy to remove and reattach. They can be completely removed for cleaning and take only seconds to put back on when you’re done using the container.
Durable stainless steel interior construction
The interior of this thermos is constructed of the same material that high-end kitchen products are made of, 18/8 stainless steel. This means it is capable of resisting rust and corrosion for a very long time. When it comes to durability and toughness, you can’t do much better than stainless steel. It’s also non-porous, so it won’t absorb odors or tastes from past contents. The stainless steel interior also means that you won’t have to worry about dangerous chemicals like BPA leaching into your beverages.
Sweat-proof design
This is one feature that many consumers love about the Thermos Stainless King Food Jar, as well as other Thermos products. The exterior of the food jar is designed to be sweat-proof, which means it will stay dry even when filled with cold liquids or foods. You can put this jar in your bag without having to worry about a mess!
Light-Weight
This is a very important advantage of the thermos. The thermos is light in weight. This property makes it very easy to carry and transport.
Drawbacks
Thermos mugs and bottles are not microwaveable.
The direct heat from a microwave may cause the bottle or mug to break or melt.
Some Thermos products have special airtight seals that keep heat in even more efficiently, which is what makes them so good at keeping things cold and hot. The downside of this seal is that it’s also a vacuum, meaning that when you open it, there’s a high-pressure difference between the inside of the container and the outside. If you pour hot coffee into your Thermos bottle too fast, it can actually suck the liquid up through the lid. Even if you do it slowly, some people report that the seal is so tight that liquid can’t get into the container fast enough.
Can’t pour coffee into them right away.
If you use a Thermos bottle to keep your coffee hot, wait five minutes before pouring it out. Otherwise, the sudden shift in temperature can cause the inner glass to crack.
Technically a thermos is only a vacuum bottle, not the container itself.
About Yeti Rambler
History
Yeti was founded in 2006 by Roy and Ryan Seiders, who were looking for a cooler that could withstand the elements and was rugged enough to handle the demands of their fishing trips. The first Yeti coolers were manufactured in a factory in the Philippines, with input from both the Seiders brothers and the factory’s engineers.
The early coolers were made from rotomolded plastic, with thick walls that held more insulation than traditional coolers. They also featured beefy rubber latches and hinges, as well as non-slip feet.
In 2014, Yeti released its first line of tumblers, which have since become an icon of the company. These tumblers feature a double-wall vacuum design that keeps liquids hot or cold for hours on end.
Outstanding features
Extra-wide mouth
The Yeti Rambler has a wider mouth than most other tumblers on the market, which makes it easier to drink from. It also makes it easier to clean and gives you the option to fill it with ice cubes or even soup if you want.
It is dishwasher safe
The rambler cup is made of stainless steel. So, you can put it in the dishwasher to clean it. You do not have to worry about the color or design fading after washing it in the dishwasher. The stainless steel body of this cup is strong enough to withstand the high temperature in a dishwasher.
It is 2X heat and cold resistant
The double-wall vacuum insulation technology that Yeti has designed for this cup enables it to keep your beverage hot or cold for hours. It can store hot coffee for up to 6 hours, and it can keep your drink cold for up to 24 hours.
Lifetime guarantee
Yeti offers a lifetime guarantee on all of their drinkware, including their Rambler Tumblers. This means that if you own a Yeti Rambler and it ever breaks, you can contact Yeti customer service by phone or email and they’ll replace it free of charge.
Drawbacks
Overpriced
Many reviewers mention the fact that a Yeti Rambler is overpriced. This is because these products are manufactured as successful competitors to cheaper mugs and tumblers on the market for daily hot and cold beverages.
No variation in size
For many consumers, choosing between a 20 ounce or 30-ounce tumbler is not an issue at all. However, others who prefer smaller cups of coffee may feel limited by the two sizes offered by Yeti.
It is not of real use in summers
A Yeti Rambler is a product with tremendous heat retention that can keep your drink hot or cold for a long time. But in the summer, having a hot drink (for example) will make it too hot to drink quickly at all.
The Key Differences Between Thermos And Yeti Rambler
Weight
Weight is by far the most significant difference between the Thermos and Yeti Rambler. The Thermos is much lighter than the Yeti Rambler. This makes it the ideal choice if you’re looking for a lightweight product that’s easy to transport.
Price
Yeti Rambler products tend to be more expensive than Thermos products. The difference in price can be quite dramatic, especially if you compare higher-end models from each brand.
Insulation
Both Thermos and Yeti Rambler products offer excellent insulation, but yeti Ramblers tend to have slightly better insulation overall. This is because they are less likely to leak air into the inside of the mug due to their special seal system.
Capacity
The 30-ounce Thermos has about 10 ounces more room for hot drinks than the 20-ounce Yeti Rambler. However, one of the biggest differences between the two models is that the Thermos lid doubles as an 8-ounce cup, meaning you can drink your coffee and leave your thermos at home. The Yeti does not have this feature, so you need to bring along a mug or other drinking vessel if you want more than 20 ounces of coffee.
Materials used
The Thermos is made with 18/8 stainless steel while the Yeti is made with 18/8 pro-grade stainless steel. This means the Yeti has less chromium and nickel than the Thermos. Therefore, the Yeti is less susceptible to corrosion than the Thermos bottle, which is another advantage over the Thermos insulated bottle.
Lid style
The Thermos has a leak-proof lid that locks for added security. The Yeti lid does not lockdown, but it does have a magnetic slider to keep it easily accessible and out of your way when you need to take a drink.
Appearance
Both Thermos and Yeti products look similar. Both have double-walled, stainless steel bodies with plastic lids and caps. The exterior of Rambler bottles is textured, while Thermos bottles are smooth. Rambler bottles come in a variety of colors, while Thermos bottles are only available in silver.
Heat retention
The insulation in the Thermos makes it capable of keeping hot beverages hot for up to 12 hours or cold beverages cold for up to 24 hours. Rambler bottles are similar in that they will keep hot drinks warm for up to 12 hours and cold drinks cool for up to 24 hours.
Why You Should Buy Yourself A Vacuum Bottle?
Keeps your cold drinks cold and hot drinks hot.
Whether you’re into iced coffee or hot tea, a vacuum bottle will keep your favorite drink at the optimal temperature all day. No more lukewarm tea or cool coffee. The latest models of insulated bottles now come with removable tea-infusers that make steeping loose leaf tea easy and convenient.
Stay hydrated.
Staying hydrated is important for maintaining good health, but it’s not always easy to drink enough water every day. In fact, many people worry about drinking too little water because they don’t want to be running to the bathroom every five minutes at work. A vacuum bottle makes it easy to stay hydrated throughout the day and also reduces the number of trips to the bathroom. With a vacuum bottle, you can take as much water as you like with you to work and sip from it whenever you feel thirsty — even if that happens to be between meetings or during lunch break.
Supporting your health.
In addition to keeping you hydrated, drinking enough water also helps support your overall health in other ways as well. It helps us lose weight (but don’t use that as an excuse not to exercise), supports skin health and flushes out toxins. Having a good vacuum bottle on hand makes it easier to get that kind of support!
Useful in all seasons.
A high-quality vacuum bottle is useful in all seasons. In winter, you can use it to make a cup of hot tea or coffee, and in summer — cool water. The same thing applies to the season of autumn when it is not yet cold enough for a hot drink, but you don’t want to drink cold water. Moreover, if you are not indifferent to the environment, this is an excellent opportunity to reduce the amount of plastic waste from disposable bottles.
The right appearance.
Vacuum bottles are available in many different designs. You can choose from different colors and various shapes and sizes. If you order online, you can even choose from different patterns. If you are looking for something more special, there are many manufacturers that offer custom-made vacuum bottles. It’s not just appearance that counts; quality is also important.
No leaking, no sweating.
Some people have experienced leaky containers or condensation while they have been out and about. With a good vacuum flask, this problem doesn’t exist – the lid has a rubber seal so that nothing leaks out and there is no condensation on the outside of the bottle.
Take it anywhere you go.
The fact that vacuum bottles are so portable means they are extremely useful for a range of different purposes. Whether you need to take something to work with you, or if you want to bring some hot tea or coffee while camping out, they are always going to be there to help you out.
Easy to clean.
The design of vacuum bottles also makes them very easy to clean no matter what the circumstances might be. This is a factor that most people tend to overlook and end up regretting later on when they realize that cleaning the vacuum bottle properly is simply not possible.
Environmentally-friendly
One of the biggest benefits of vacuum bottles is that they are extremely eco-friendly, which means that if you want to do your part in saving the environment then this is definitely something that you should consider buying. Vacuum bottles don’t contribute any kind of pollution whatsoever and are reusable as well which means that we can reduce our carbon footprint substantially if everyone started using these bottles instead of plastic ones.
Versatile
Vacuum bottles can be used for more than just keeping liquids hot or cold. For example, you can use them to steam foods like broccoli and carrots in the microwave. Just pour a small amount of water into the bottom, put your food on top, cover it with the lid, and microwave it for a minute or two. The result will be vegetables that are perfectly steamed.
Another way to use vacuum bottles is to make poached eggs. Just pour some water into the bottom of your vacuum bottle, crack an egg into a small dish and add it to the bottle. Place the lid on top and microwave it for about one minute to create a perfectly poached egg without having to break out any pots or pans.
Circumstances When A Vacuum Bottle Is Essential
When traveling
A vacuum bottle comes in handy during road trips, flights, bus rides, train trips, and any other form of transport. It is perfect for keeping your drinks hot or cold for the duration of the trip.
At work
If you have to travel to work every day, it is convenient to carry a vacuum bottle with you on your commute as it will keep your drinks at the desired temperature all through the day.
In school
Vacuum bottles are great for students because they can use them to store all kinds of beverages throughout the day at school. They can also use them to store beverages when they are going out on a picnic or a trip with friends and family.
In the office
Having a vacuum bottle in the office means that you can always have access to hot water or tea or energy drinks all through the working hours of the day, no matter where you work from!
Conclusion: Which One Is Better?
The Thermos Stainless King and the Yeti Rambler are pretty much neck-and-neck in terms of performance. The Thermos is a little better at keeping things cold, while the Yeti is slightly better at keeping things hot.
But the Yeti feels a little more durable, has a more leakproof lid, and holds half as much again as the Thermos.
The Thermos is a bit cheaper, though. And if you don’t need to take such large amounts of coffee with you, it’s the better buy.
