While most of the mugs on our list work well for hot or cold beverages, they are generally better at one or the other—but that’s not the case with this mug from Zojirushi. It retains drink temperature for at least six hours, no matter if you take your coffee hot or iced. Our experience with the mug was even better than the company advertises: Coffee was warm enough to drink nearly 12 hours after brewing. The Ember Travel Mug²'s best design feature is the lid: It only needs a push to open, is leak-proof, and lets you sip from any side of the mug. Furthermore, the mug's design is ergonomic. It's wider at the top than the bottom and is coated with a matte finish, making it easy to grip and comfortable to hold. Like most Yeti products, the Rambler effectively keeps drinks hot for around 10 hours or cold for close to 20. It's also sold in more than 10 colors from neutrals to vibrant hues, so you can find one that suits your style.

Plus, the lid is easy to take apart when in need of a wash. Just untwist the top lid, turn the handle underneath the lid, and pull. The inner piece should come right out. Then throw all three pieces of the mug in the dishwasher (yeah, it’s dishwasher safe) and voila—it’s ready for the next use. We’ve also been washing the mug by hand, however, the lid is not as easy to clean this way as others we’ve tested. There are some small spaces inside the cap that are a little difficult to reach. It’s not a deal-breaker, especially since everything is dishwasher safe, but it’s something to note. Stanley Classic Trigger-Action Travel Mug 12oz Cap Apart

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. The comforting feel of smooth steel as you reach for your hot coffee is a familiar cool touch but strangely comforting. You take a sip as you stare out of your Airbnb at the haphazard roads of Hanoi, where you watch pedestrians escape death nonchalantly. You feel at ease since it's a handfeel you've gotten used to.

The Stanley Classic Trigger-Action Travel Mug is made with durable 18/8 stainless steel that doesn’t hold onto coffee smells or stains. It also touts double-wall vacuum insulation that keeps your coffee or tea hot all morning. Stanley claims it’ll keep drinks warm for up to five hours, and we’re happy to report that this has been a pretty accurate estimate during our testing. It’s done a great job of keeping our java warm enough to savor all morning. 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. Unlike traditional bottles/flasks, you only have to use one hand to access your drink. Just press the button on the side of the Trigger Action Travel Mug and the clever lid opens up. While I don't normally drink hot drinks, I have found that the mug keeps drinks hot for around five hours and more. This is great for slow-drinkers who like to sip on something throughout the day.

The flask is a stainless steel double-wall construction and BPA-free. This means that it regulates the temperature of the liquid. This is great for using when you only have one hand free, ideal for walking along with a walking pole for example. No need for two hands to flip a lid or screw a cap off. We’ve taken this mug out on a number of occasions now, and in typical Stanley style, the Classic Trigger Action Travel Mug is a bit special and has one very handy feature.The leakproof claim is impressive, and indeed, there hasn't been even a drop leaking from it so far. However, after drinking from the lid, you'll notice drops of liquid gathering around where the mouth is. While this is negligible if you are drinking H2O, you risk staining the insides of your bag with coffee and the like. SINGLE HANDED - Besides keeping your drinks hot or cold for long periods of time, this super handy mug is leak proof and can be opened/closed with just one hand.
