While writing this Zojirushi thermos review, we were smitten by this product’s simplicity combined with functionality. You have probably heard the saying that “beauty happens when form follows function”; this elegant 20oz. Zojirushi thermos mug is a perfect example, with a tall, sleek stainless-steel body that comes in 17 designs and colors, including a beautiful Garnet Red, unusual Coral Pink, and a very feminine Pearl Pink. More neutral choices are also available such as brushed Stainless Steel, striking Cinnamon Gold, and a Silky masculine black. These thermal mugs also come in themes such as the Sweets Purple pattern, featuring donuts, lollipops, popsicles, and the mint-themed Hedgehog pattern that features kissing cartoon hedge-hogs.

Of course, the Zojirushi thermal flask is much more than just a pretty mug, as it boasts a vacuum design with superior heat retention, a snap-on safety lock on the lid to prevent spills, and a flip-up lid for easy sipping when you are on the go.

Review

We were very impressed by the prices and overall functionality, and beauty of the Zojirushi coffee mugs we saw online. It seems customers thought the same, giving the thermos consistent 4-to-5-star reviews. In 2019, a reviewer in Esquire magazine Trusted Source Zojirushi Makes the Best Stainless Steel Travel Mug for Coffee We swear by this vacuum-insulated mug for hot, hot coffee for hours on end, thanks to its innovative lid. www.esquire.com called it “the best mug you will ever own because of its innovative lid and ability to keep coffee hot for at least six hours. It also keeps cold beverages icy for just as long.

Overall performance and design

The lid on the Zojirushi travel mug is also impressive. There is a slotted sliding button on the side of the lid to unlock and lock it down. A tiny infographic reminds you if it is locked or unlocked, so you never forget to screw the thermos lid on as tightly as possible after taking a sip. The lid is flip-up style with a button to activate.

There is an ergonomically friendly angled stopper in the thermos that allows you to easily sip from the beverage, without spilling. The plugin the lid of the unit helps to seal the thermos contents once you snap it shut again.

The Zojirushi thermos flask is a tall narrow flask and not really a mug. The stainless thermos is just round enough at 2.87 inches to wrap your fingers around. If you want to think of this as a coffee mug, you can, but remember, it is a 9.88 inches tall coffee cup.

On top of all of this, the lightweight of all stainless-steel Zojirushi thermos is quite attractive, with 17 color/design options to choose from when shopping online.

Capacity

The capacity of the Zojirushi thermos mug is 600 grams  (20oz.). This amounts to be at least two and a half eightounce cups of coffee, tea, or another beverage.

Opening

Zojirushi Thermos Review: New Travel Partner

Zojirushi flip-open lids are designed to release and hold, then flip open. This 2-step lid release allows condensation on the lid gasket to fall back into the mug instead of splattering.

The mouth of the Zorjushi thermos mug is made out of BPA-safe plastic and has a lip that curves upwards to meet your mouth, so you end up drinking rather than wearing the liquid. An air vent balances the volume inside the vessel as you drink to not splash on you. It disassembles into four pieces, the lid, spout, stopper, and rubber ring for easy cleaning.

You can also screw the lid off of the stainless steel part of the thermos lid to insert items such as ice cubes or teabags. It’s not just for coffee!

Material

This safe and easy-to-maintain thermos is made out of stainless steel and has a non-stick coated interior to prevent stains from coffee, tea, or salt. The lid is made of safe BPA plastic.

Dimensions and weight

This super-light unit only weighs 8 ounces and is a tall slim vessel that is 87×2.87×9.88 inches. It fits nicely into a bag or cup holder, and as it is so light, you could easily take it on a hike.

Compact design takes minimal space while maximizing capacity.

Vacuum insulation

The vacuum insulation in this mug keeps hot liquids at 189 degrees Fahrenheit for one hour and at 160 degrees for six hours, which of course, means that this is the mug that is going to go the distance for you during a long commute or hike. The MCAUSA National Coffee Association Trusted Source How to Brew Coffee Great coffee starts with great beans. www.ncausa.org of the USA recommends drinking your coffee at a slightly more temperature 140 degrees to get the most out of its flavor. One of its criticisms is that it keeps the coffee too hot, which for some coffee sippers takes away from the caramel and salty flavors in the brew. In addition, coffee that is too hot really does increase the risk of a lip or tongue burn or skin burn if you spill the coffee on you anyway.

The vacuum insulation of this mug is also amazing as it keeps icy drinks icy for about six hours too, so if you prefer iced tea or cold brew, the vacuum insulation in this mug can keep it cool for you.

The Zojirushi flask thermos’ ability to hold the heat or cold is thanks to its technology which has a doubled layered interior encased in a stainless steel bottle. The locking system on the lid is a safety mechanism designed to keep the hot vacuum insulated beverages from dripping on you.

Ways of using

You can put any beverage or meal that you want in the Zojirushi flask thermos. The opening of the flask is a bit narrow once you take the lid off, but you can put soup or noodles in it, as long as you plan to pour it into another container. You can also store ice in it for about four hours.

Ease of maintenance and cleaning

Zojirushi Thermos Review: New Travel Partner

Lid completely disassembles for easy and thorough cleaning.

After you are done with your beverage, remember to dump it out so that any leftover liquid does not sit and grow inside the flask and create odors. It is also a good idea to keep the four parts of the lid together at all times, as losing one part (especially the ring) could cause your thermos to leak.

The interior of the thermos is easily cleaned with a bottle brush, and the lid can be disassembled into four pieces. It is especially important to inspect the ridged interior of the ring that goes around the flask for mold. A simple solution of soap and water should serve to clean every part of the thermos. It is probably not a great idea to put it in the dishwasher, even though it is made of quite durable materials, as the narrow opening of the flask makes it hard for sprayed dishwasher water to reach its interior.

Warranty

The Zojirushi flask thermos comes with an impressive 5-year warranty, which is one of the best offers for a warranty for a thermos online.

Price tag

Zojirushi thermos mugs are usually priced in the $30 range, which is a real deal considering its great design, look, and ability to insulate fluids at a preferred temperature for hours.

Other features

Perhaps the most impressive feature of the Zojirushi thermos mug is how tightly the top seals and prevents heat from escaping. Often with this type of mug, the beverage can spurt back at you when the vacuum seal is popped, but in this case, the design has an air vent that prevents this type of surprise.

PROS CONS
  • Attractive, sleek appearance
  • 17 colors/themes
  • Leak-proof lip
  • Flip-Up lid

 

  • May keep liquids too hot
  • No handle

Conclusion

After writing this Zojirushi thermos mug review, it became apparent that it is one of the best buys for a thermos at only about $30.00 not only because of its superior leak-proof, safety, and insulating features, but also because it is a very good-looking thermos that comes with a variety of finishes, colors, and designs. Its only flaw is that it might work too well when it comes to keeping beverages hot.
