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 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 bottle comes in two sizes, a 16oz and 20oz version. The one I am reviewing is the 16oz version. With the bottle in hand, the 16oz seems like the more reasonable size to be drinking from. Prefer iced coffee? Then a travel mug that has a straw might suit your palette more. This model fits in most cup holders and can keep your drink cold for up to 12 hours. You can use the removable plastic straw with the Tritan lid or not,depending on your preference. The one design flaw, however, is that there is no way to completely seal the lid since the hole doesn't include a cover or flap. The 16oz also fits well into water bottle compartments like the one on the TOM BIHN Synik 30, which makes me think bigger isn't always better. Fits nicely into the water bottle compartment in my TOM BIHN Synik 30. Material

This 16-ounce travel mug works for both hot coffee, iced coffee, and cold brew, and it comes at a budget price. It's designed with a double-wall construction to keeps drinks at their temperature for longer than a non-insulated cup; however, it’s not made for all-day temperature regulation like some stainless steel mugs. I found hot coffee to be lukewarm just two hours after brewing. The good news is that the mug is microwave-safe, so you can easily reheat drinks should they cool off. 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. While the stainless steel bottle doesn't hold onto coffee smells or stains, the lid is plastic; therefore, it will do so. It's important to clean it regularly. The cleaning of the bottle is effortless since the lid comes apart, resulting in no hard-to-reach places.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. 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. Conclusion 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. 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.

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. If your morning routine always starts (and ends) with a hot cup of joe, you’ll be pleased to meet the Stanley Classic Trigger-Action Travel Mug 12oz. Of course, you can use it for other beverages like tea, lemonade, or apple juice (carbonated drinks are not recommended). But we’ve found it to excel most as a portable coffee mug—keeping that liquid gold warm all morning whether we’re at work or on the go. Stanley Classic Trigger-Action Travel Mug 12oz with Coffee 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. 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. I tested the 16-ounce model firsthand and confirmed that it lives up to the brand's claims about temperature retention. Hot coffee stayed warm and drinkable for seven hours, cold coffee lasted 10 hours without ice, and ice water remained refreshing for more than 30 hours. With that in mind, temperature retention varies slightly depending on the size of the mug you buy.The S’well Stainless Steel Traveler Mug is inarguably one of the best-designed travel mugs on the market today. Thanks to S’well’s high-end, triple-wall technology, you can rest assured that your drinks will maintain their ideal temperature for hours on end. I found that it performed exceedingly well. Coffee stayed hot for 12 hours and, after adding refrigerated coffee without ice, it was still cold 30 hours later.
