The Best Travel Mugs for Hot or Cold Sips on the Go

Other Options We Tested

• Yeti Rambler Mug: Yeti makes a number of reliable travel mugs—not to mention the brand's beloved coolers—but the Rambler mug has too many shortcomings for us to recommend it, starting with its poor insulative properties. The hot coffee we brewed lost temperature rapidly in the mug and, because it's made with stainless steel, it couldn't be reheated in the microwave. Additionally, the lid is not leakproof, which is a feature that's easy to find in a number of other travel mugs out there.
• Ello Campy Travel Mug: The Ello Campy Mug is a stylish, large-capacity option that many customers may enjoy, especially those into the outdoors. While it doesn't have any major defects, it didn't quite make the cut for this list. We found that the paint can chip easily and that it's tricky to clean. On top of that, it's too large to fit in many car cupholders.

What to Look for in a Travel Mug

Lid Style

It doesn’t matter if you’re drinking coffee, tea, or water—every sip from your travel mug should be smooth and easy. That’s why it’s important to figure out the lid style that best suits you. Some of the top options include flip lids, thumb-sliding lids, push-button lids, twist lids, and straw lids. Each one has its own advantages and disadvantages. Customers who prioritize durability or preventing spills, for instance, should choose a more secure style, like a twist lid. Others who want to seamlessly drink from their mug while on the move may prefer a lid that can be opened with one hand. Luckily, lid style does not affect price, so every option should be on the table when you start looking for a travel mug. Many brands also sell lids individually so that users can have multiple options at their disposal.

Temperature Retention

All too often we take a sip of coffee and find it’s gone lukewarm. A reliable travel mug can thwart that dreaded, flavorless middle zone and keep your coffee at the ideal temperature for hours, no matter if it’s hot or iced. Vacuum-insulated mugs, which are typically made from stainless steel, offer the best performance when it comes to temperature retention, while plastic and silicone are the least effective materials. When buying, think about the type of coffee you drink most often (hot or iced) as some mugs are better designed for one or the other.

The length of time that a mug keeps drinks hot or cold is often listed in its product details, but keep in mind that this figure is often based on the item being preheated or precooled before use. We also asked Graham Nearn of the Stanley brand what temperature range the company defines as "hot" and "cold." He told us that when Stanley says a drink stays hot for a certain amount of time, the liquid must be between 140 to 203 degrees; for a drink to be considered cold, it has to fall between 39 and 50 degrees.

Size

Travel coffee mugs come in a variety of sizes. The average capacity is around 16 ounces, though the range extends far on either side of that. Some are no bigger than a regular at-home coffee mug; others are large enough to keep you caffeinated the entire day. Brands often manufacture the same mug in multiple sizes, so if a specific one catches your eye, you can likely find it in a size you love. Customers interested in larger mugs should see if it is microwave-safe or able to retain heat well; otherwise, they may be sipping a lot of cold coffee. Finally, for those who plan on taking their mug in the car, check out customer reviews or product details to ascertain if a mug can fit in your cupholders.

Material

While most travel mugs are made from stainless steel, options are far from limited when it comes to material. Other possibilities include plastic, glass, silicone, ceramic, and bamboo. This choice naturally affects a mug’s aesthetic, as well as larger factors like price, durability, how the item is cleaned, how long it retains heat, and whether condensation appears on the outside. What factors are most important to you? If you want a budget-priced mug that can go in the microwave, plastic is likely the best material for you. If durability and heat retention are higher priorities, you may want to stick with the stainless steel route. Also keep in mind the downsides that certain materials have. Plastic mugs, for instance, can stain and retain coffee odors, while some stainless steel mugs may unfavorably alter the flavor of your coffee.

If you sift through a list of travel mugs, you will likely come across the phrase "18/8 stainless steel." This denotes a type of stainless steel made from 18 percent chromium and 8 percent nickel. Graham Nearn of the Stanley brand says 18/8 stainless steel is often used for drinkware because it's "food-grade, durable, and resistant to corrosion."

Leak-Proof vs. Spill-Proof

Whether walking to class, embarking on a long hike, or heading out for the daily commute, it’s easier to transport a mug if it can be kept inside a bag; that’s where leak-proof travel mugs come in handy. They prevent even the slightest drop from escaping into your bag, no matter what. Make sure to read customer reviews beforehand, however, as some items advertised as leak-proof may not actually be up to the task. There is also a difference between leak-proof and spill-proof. Mugs labeled as spill-proof only prevent major spills from occurring; they are not safe to store in bags since they can still leak.

Design

Taking a travel mug’s design into consideration involves two different paths. First, you can think about the item’s shape or silhouette. Do you want a mug with a handle? Or one thin enough to slide into a bag or backpack? Second, design also involves the many colors and patterns found on the outside of a mug. There is an array of options, from fun and playful to chic and striking, that can convey your personality with every sip.

Price

Not only are most travel mugs affordable, but they also help customers save money by cutting down on daily trips to the coffee shop. The only type likely to break the bank are electric travel mugs. Other than that, budget picks are widely available both in-store and online. Some mugs cost as little as a bag of coffee beans. Size does generally impact price, however, as larger mugs tend to cost more than smaller ones, even if they are the same model. Expect plastic mugs to be the cheapest option, while glass, stainless steel, and ceramic are all slightly more expensive. 

Types of Travel Mugs

Coffee Mug

When picturing a travel coffee mug, most envision a tall, tapered item similar to a reusable water bottle, but there are actually many options designed to look exactly like the mugs we use every day at home. Items in this category provide the feel and comfort of a regular coffee mug but with added heat retention and the luxury to take your joe on the go. Because they are smaller in capacity than most travel mugs (usually around 12 ounces), they are also slightly more affordable. Unfortunately, coffee-mug-style travel mugs aren’t leak-proof and don’t fit in cupholders because of their handles.

Portable Coffee Maker

Truly defining on-the-go coffee, there is a category for travel mugs that additionally function as portable brewing devices. They allow users to make coffee and drink it all from the same bottle. This is certainly a less common variety, but it’s still worth consideration, especially for frequent travelers and campers. The majority of portable coffee makers work like French presses. Aptly named “travel presses,” they immerse coffee grounds in water and then push them to the bottom of the mug via a built-in plunger. The second most common type of portable coffee maker utilizes a pour-over brewing method instead.

Tumbler

Well known for their smooth exterior, tumblers are the most popular subcategory of travel mugs. They never have a handle and the body usually tapers to a narrow base, both of which make them cupholder friendly. Tumblers can be used for both hot and cold beverages, but they are especially popular for iced coffee. Many have straw lids for easy sipping. Customers may be familiar with tumblers in other types of drinkware, as they are also used for cocktails, iced tea, lemonade, and general home use.

FAQs

What is a vacuum-insulated mug?

The phrase “vacuum-insulated” pops up all over the place when searching for travel mugs. It’s also commonly used with another phrase: "double-walled." Both labels denote that a travel mug is built with two different layers, an inner wall and outer wall, and that the space between the layers is partially evacuated of air, creating a vacuum. This design allows drinks to retain their temperature for a longer period of time because they are less exposed to the outside air.

Can I make my travel mug retain temperature longer?

We all want the most out of our products, and this one small tip goes a long way: preheat or pre-cool your travel mug before use. Taking a few extra minutes to let hot or cold water sit in your mug will prime the material for better temperature retention. You can pour hot water from the tap or even boil it for an added boost of heat, all while your coffee is brewing.

How do I clean my travel mug?

Before cleaning, consult the product details or instruction guide to see if the item is dishwasher-safe. This is a common benefit of glass and plastic travel mugs but not stainless steel. If your mug isn’t dishwasher-safe, don’t worry. Cleaning is still quite easy. A simple daily cleaning only requires scrubbing with dish soap and a sponge or gentle brush. Avoid using steel wool brushes and harsh household cleaners on stainless steel mugs. For a more thorough job, allow a solution of vinegar and baking soda to soak inside the mug for several minutes, then rinse and clean with dish soap before using.

Can I add milk to my coffee if it’s in a travel mug?

Most brands advise against putting milk or creamer in thermoses unless it's for a brief amount of time. Bacteria can develop when dairy products are stored at warm temperatures, especially if the travel mug isn't properly cleaned. Graham Nearn of the Stanley brand echoed this thought, telling us: "We don’t recommend putting milk or dairy products in Stanley vacuum bottles or food jars for extended periods of time, as bacteria growth can occur at certain temperatures."
