From sweltering summer days to subzero blizzards, die-hard iced coffee lovers crave their favorite caffeinated drink no matter the time, season, or temperature. That’s where reusable iced coffee cups come in handy. They are a great way to save money and reduce waste by cutting back on trips to the coffee shop; plus, they allow users to take their drink on the go, whether it be to the office, a get-together, or a hike.
We tested an array of reusable iced coffee cups in our Lab and sent some home with our writers to see how they fared over several weeks of use. Each coffee cup was rated on its design, size, functionality, effectiveness, and value. From there, we narrowed down the best options to create a list you can trust.
For a delicious drink anytime and anywhere, here are the best reusable iced coffee cups.
Best Overall: Contigo Autoseal West Loop Vacuum Insulated Travel Mug
Effective auto-lock and anti-spill lid
Can lock and unlock with one hand
Keeps drinks hot/cold for hours
A little wide for smaller hands
The Contigo Autoseal West Loop offers everything you could want in a reusable iced coffee cup, from long-lasting durability to a sleek design, making it our top pick. Among the biggest perks is its leakproof design, which one of our testers verified by carrying around a full mug in her bag and finding it drip free at the end of the day.
The West Loop performed even better than advertised when it came to insulation. We found our coffee to be piping hot for three hours and still warm enough to drink six hours after brewing. When we tested it with ice water, ice cubes stayed in the mug for 12 hours and the water remained refreshingly cold after 20 hours. You can purchase the West Loop in a color that fits your personality, too; there are eye-catching shades like Monaco and Passion Fruit, as well as timeless options like black and stainless steel.
While the mug is a little wide, it easily fits in car cupholders. Perhaps the only other drawback is that the body is hand-wash only. The lid is top-rack dishwasher safe, however.
Price at time of publish: $30 for 20-ounce travel mug
Capacity: 16, 20, and 24 ounces | Dimensions: 3.5 x 7.8 inches (16-ounce model) | Color Options: Yes | Warranty: Lifetime limited
"The Contigo Autoseal travel mug is a great option for coffee lovers—especially those who go through 20 ounces (or more) each morning." — Suzie Dundas, Product Tester
Runner-Up, Best Overall: Yeti Rambler 20 oz Tumbler
Large capacity and fits cupholders
Multiple color options
Prone to leaking
Easy to scratch
Initially known for high-end coolers, Yeti has ventured into drinkware with its line of Rambler products. The Rambler Tumbler is our favorite for iced coffee because of its sliding lid and cupholder-friendly shape. The tumbler keeps drinks hot or cold for several hours due to its double-walled vacuum insulation. Despite being on the pricier end, it’s popular and highly rated, with customers praising its durability and that it can go in the dishwasher.
You can purchase it in three sizes—10, 20, or 30 ounces—and 12 colors, ranging from white, black, and stainless steel to more striking options like Seafoam and Peak Purple. The only drawback is that the lid is not leakproof, so keep that in mind before stowing it in a bag or backpack.
Price at time of publish: $35 for 20-ounce tumbler
Capacity: 10, 20, 30 ounces | Dimensions: 2.75 x 4 x 7.8 inches (30-ounce model) | Color Options: Yes | Warranty: 5-year limited
Best Gift Option: County Line Kitchen Cold Brew Mason Jar Coffee Maker
Can brew coffee and tea
All parts dishwasher safe
Not as easily portable
Lid can become tight
Whether it’s a holiday, birthday, or just-because day, there’s never a bad reason to give your coffee-loving friend or family member this Mason jar cold brew maker. All you have to do for delicious cold brew is scoop the desired amount of coffee grounds into the steel filter, fill the jar with cold water, and let it sit overnight in your refrigerator. It took us no more than a few minutes to set up and, after refrigerating it for 36 hours, the cold brew was smooth and flavorful, just like many online reviews mention.
It's also an excellent gift option because Mason jars suit a variety of kitchen decors. County Line Kitchen keeps the price reasonable too, so you can throw in a bag of coffee beans if gifting, many of which are roasted specifically for cold brew. Our product tester added that the stainless steel filter eliminates the need for paper filters, cutting down on waste and saving a little money in the long run.
Even though the item is extremely easy to use, we found the instruction booklet vague at points, especially when it comes to the ratio of coffee grounds to water. As a solid starting point, we used a ratio of 4 cups of water for every 1 cup of coffee.
Price at time of publish: $32 for 2-quart
Capacity: 32 and 64 ounces | Dimensions: 4.5 x 10 inches (64-ounce model) | Color Options: No | Warranty: 90 days
"The County Line Kitchen Cold Brew Coffee Maker is simple to use, looks great just about anywhere in the house, and delivers on delicious cold brew coffee. It’s really a great return for the price." — Cheyenne Elwell, Product Tester
Best for Travel: Bubba Envy Insulated Stainless Steel Tumbler with Straw
Lid seals tightly
Fits in car cupholders
Keeps drinks cold or hot
Can't close hole on lid
Not only is the Bubba Envy convenient for taking iced coffee on the road, it can also keep drinks hot for several hours and the straw is large enough to drink all kinds of smoothies. Overall, the item is versatile, durable, and reasonably priced—all of which led our testing team to give it a strong review.
We found that ice water stays cold for more than 20 hours and hot liquids maintain a suitable temperature for around five hours. The cup is made of stainless steel so it resists stains and odors, which is often an issue for plastic travel mugs. Another detail our tester particularly likes is the indents on the outside of the cup that make it both comfortable to hold and ensure that it fits in a cupholder.
Unfortunately, the spout doesn't have a cover if you choose to remove the straw, so the mug can't be thrown in a bag or backpack when full.
Price at time of publish: $18 for 24-ounce tumbler
Capacity: 18, 24, and 32 ounces | Dimensions: 3.93 x 3.62 x 10.54 inches (24-ounce model) | Color Options: Yes | Warranty: Lifetime
"If you’re looking for a durable travel mug that’s designed to hold both hot and cold beverages, the 24-ounce Bubba Envy Insulated Stainless Steel Tumbler is a solid option at a price you can afford." — Rebekah Joan, Product Tester
Best With Straw: Klean Kanteen Insulated Tumbler With Straw
Eco-friendly metal straw
Fits in cupholders
Shorter heat retention
For those looking to reduce their carbon footprint, cutting back on plastic straws is a great place to start, and Klean Kanteen makes it easy thanks to this reusable mug with a steel straw. The California-born company is known for its eco-friendly products, having manufactured the first stainless steel personal water bottle back in 2004. The straw they use here is capped with silicone to make drinking more comfortable. A small downside, however, is that our testers say dust and lint often stick to the straw.
It's also not the best when it comes to temperature retention. The Klean Kanteen kept drinks hot and cold for an average amount of time compared to all of the mugs we tested, yet it was sufficient enough for us to recommend the item nonetheless.
This mug also stands out because of the many fun color options you have, along with standard choices like black and stainless steel. It's only available in one size, 16 ounces, but we found this large enough to satiate our daily coffee craving. The last perk our testing team noted is that the mug leaks very little even when you shake it. It's not 100 percent leakproof but still dependable.
Price at time of publish: $28 in emerald bay
Capacity: 16 ounces | Dimensions: 3.5 x 9.85 inches | Color Options: Yes | Warranty: Lifetime limited
Best for Keeping Cold: Hydro Flask Wide Mouth Flex Sip Lid Bottle
Easy to drink on the go
Keeps drinks hot/cold for hours
Not the best lid for commuting
Many coffee drinkers know the frustration of sipping lukewarm, watered-down iced coffee. That won't be an issue with the Hydro Flask Coffee with Flex Sip Lid. It performed well in a number of areas in our testing process, and one of them is certainly temperature retention. We filled the mug with ice water and found the ice cubes intact more than 12 hours later; the water was still cold after a full 24-hour day. And if you want to switch up your daily cup of joe, this pick also keeps beverages hot for up to 12 hours thanks to its double-walled thermal insulation
It's available in three sizes—12, 16, and 20 ounces—as well as more than a dozen colors. Expect the Coffee Flask to be a long-term purchase; the product is backed by a lifetime guarantee and we found the stainless steel solid and durable. We confirmed that the mug is leakproof by carrying it around in a bag for several hours and even shaking it upside down over the sink. Keep in mind, however, that cleaning it in the dishwasher is not recommended, so you'll have to wash it by hand.
Price at time of publish: $33 for 16-ounce bottle
Capacity: 12, 16, and 20 ounces | Dimensions: 2.9 x 7.9 inches (16-ounce model) | Color Options: Yes | Warranty: Lifetime limited
Of all the mugs we tested, this is one of the best at keeping drinks hot or cold. I think the price is really fair too considering how durable the stainless steel feels and that the mug comes with a lifetime warranty.
The Contigo Autoseal West Loop checks all the boxes: compact, affordable, leakproof, and it keeps your iced coffee cold. It's even easy to drink from while on the go, all of which earns it our top spot. Customers looking for a larger option will likely prefer the Yeti Rambler Tumbler—but keep in mind that the item is not leakproof.
How We Tested
We purchased and tested more than a dozen reusable iced coffee cups to provide an accurate assessment of the best options available today. Our testing team measured how long the cups kept beverages cold, gauged the durability of the materials, and took the cups outside the house to see what it was like using them while on the go. The majority of iced coffee cups were also tested side by side in our Lab. Each cup was then given a one to five rating on its design, size, functionality, effectiveness, and overall value so that we could narrow down the list above.
Other Options We Tested
- Soma Brew Bottle: The Soma Brew Bottle is a unique option because it's a two-in-one mug and brewing device. Unfortunately, the glass body broke during the testing process, so durability concerns are the main reason it can't be confidently recommended.
- Ello Campy Stainless Steel Travel Mug: One too many shortcomings prevent us from including the Ello Campy Mug on this list. Our product tester found that the paint can chip easily; plus, the lid is hard to clean and the mug itself is too large for some cupholders. There are still several positives, however, like its rustic aesthetic, large capacity, and sturdy handle.
What to Look for in a Reusable Iced Coffee Cup
One of the first decisions to make before buying a reusable iced coffee cup is what size you want. Some people prefer larger bottles because they don't need to be refilled as often; others prefer smaller ones that can fit in bags, backpacks, and purses. Think about how much coffee (or other beverages) you drink in a day and then choose the size that works best for you.
Do you want a lid that makes it easy to sip while on the go? Or do you prefer using a straw? How important is it for an iced coffee cup to be leakproof? Questions like these will help you choose between flip lids and trigger-action lids (great for walking and driving), twist lids (the most secure), or bottles that come with straws.
Fortunately, it's quite easy to find iced coffee cups that are entirely leakproof. Whether you're walking to class, going on a hike, or simply making your daily commute, it's easier to transport a reusable cup if you can throw it into your bag. Make sure to read customer reviews beforehand, however, as some items advertised as leakproof may not actually be up to the task.
How do I clean my reusable iced coffee cup?
For most reusable iced coffee cups, 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. For a more thorough clean, 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 again. It’s worth consulting the product details or instruction manual provided with your reusable iced coffee cup to see if it is dishwasher-safe. This is a common benefit of glass and plastic mugs but not always stainless steel. If your reusable iced coffee cup isn’t dishwasher-safe, don’t worry. Cleaning is still quite easy.
What is a vacuum-insulated mug?
The phrase “vacuum-insulated” pops up all over the place when searching for reusable coffee cups and mugs. It’s also commonly used with another phrase: “double-walled.” Both labels denote that a reusable coffee cup 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 outside air.
Can I put milk in a reusable coffee cup?
The short answer is yes, you can add milk or creamer to your coffee in a reusable iced coffee cup. Storing dairy products at warm temperatures can lead to bacteria growth, however, especially if the coffee mug is not cleaned properly afterward, so if you do add milk, make sure it’s only in the mug for a short amount of time and that the mug is cleaned thoroughly after drinking. Check if the manufacturer advises against adding milk or has any recommendations for cleaning afterwards too.
What’s the difference between iced coffee and cold brew?
Iced coffee and cold brew are different in the way they are prepared and in overall taste. Traditional iced coffee is made by brewing coffee hot first and then chilling it with ice afterward. Cold brew, on the other hand, is made by steeping coffee beans in nothing but cold water for several hours. This makes cold brew smoother in taste, lower in acidity, and able to stay fresh for a much longer period of time than iced coffee.
