Insulated water bottles are great for traveling, long hikes and those with busy schedules thanks to their ability to keep hot drinks hot and cold drinks cold for extended periods. The best insulated water bottles are durable, easy to clean and not too heavy, so you can tote them around with you. They come in a wide variety of styles, capacities and colors and many let you choose your drinking spout and have features like handles or non-slip sleeves. And let us remind you that a reusable water bottle purchase helps reduce your environmental impact and is easier on your wallet. (Those single-use water bottle purchases really add up!)

In the Good Housekeeping Institute Kitchen Appliances and Innovation Lab, we've tested thousands of beverage-related products in the last couple of decades. In our most recent side-by-side Lab test, we tested 37 water bottles, enlisted over 40 consumer testers and utilized more than 1,031 ounces of water. Through our in-Lab and real-life testing, we were able to narrow down the long list of insulated water bottles on the market to this batch that excelled in temperature retention, durability, cleanability and so much more.

Pros
- Performed very well in Lab testing
- Cap of drinking spout can hook onto handle
- Sturdy handle
- Lightweight design
Cons
- Could benefit from a non-slip bottom
While Stanley Cups are having a viral moment on Tiktok, we want to introduce you to our top-tested water bottle from the same brand — the Stanley IceFlow. GH test engineer Alec Scherma found it to be one of the more unique bottles out there. The drinking spout's design allows for faster drinking and features an easy screw-off cap.
The bottle's handle is extremely sturdy. Though it's close to the spout, it rotates down so it's not in the way while drinking. It also features a hook that holds the bottle's cap "I thought the design of the lid was super smart where you can hook it onto the handle and it stays on there pretty securely. You can even drink with the lid on the handle!" said one tester. While this bottle is dishwasher-safe, you can also remove the entire mouthpiece to hand wash it.
"I like how light this water bottle is and it still keeps my ice water pretty cold throughout the day," said a tester. "I also love the 'fast flow lid.' I love this kind of water bottle sip." Some testers noted that it would have been nice if the bottle had a non-slip bottom or sleeve because the bottle can be loud if slammed onto a countertop.

| Capacities available | 16, 24, 36, 50 ounces |
| Compatible mouthpieces | Twist-off cap spout |
| Material | Double-wall vacuum insulated, recycled stainless steel |
| Dishwasher-safe | Yes |
Pros
- Comfortable, wide handle for easy carrying
- Did not dent or leak in Lab testing
- Comes in a variety of colorways
Cons
- Mouthpiece may need some hand washing to fully ensure it's cleaned
The Takeya Originals Water Bottle comes in multiple sizes and colors, but we especially recommend this 24-ounce option for how easy it is to transport and for its affordable price. The cap is easy to unscrew, the cap is easy to drink out of and its matte finish makes it easy to grasp.
The wide mouth means the bottle is easy to fill and clean. It's dishwasher safe, but we have found after long-term testing that the mouthpiece needs some hand washing to ensure all nooks and crannies are fully cleaned (especially if you wear lipstick while drinking from it).
In our Lab tests, this bottle didn't dent or leak, and one consumer tester noted, "I used this when going to the gym, and I loved that it had a big handle to hold the bottle when going between places! It also didn't have any leakage when holding from the handle, which impressed me as well."
| Capacities available | 18, 24, 32, 40 ounces |
| Compatible mouthpieces | Twist-off cap spout |

Pros
- Chug cap is easy to drink from
- Bottle resists sweating
- Didn't leak and retained temperature well in Lab testing
Cons
- Didn't fit in a consumer tester's car cup holder
The Yeti Rambler is a highly versatile insulated water bottle that is offered in a variety of sizes, shapes, drinking spouts and colorways. This 26-ounce Rambler is a great everyday option that's comfortable to hold, doesn't sweat and is easy to drink out of, especially with the chug cap drinking spout. We especially love that the lids are all interchangeable among the various Rambler bottles that range in size from 12 ounces to 64 ounces. This water bottle is also dishwasher-safe for easy cleaning and the wide mouth also makes it easy to wash by hand — and add ice cubes.
In Lab tests, this water bottle didn't leak and retained temperature rather well. We had a few consumer testers try this bottle, and one said, "I used it while traveling during the holidays. It fit well into the water bottle pocket of my backpack. The handle on the bottle made it easy to grab and carry. It definitely kept my water cold throughout the entire day. It did not fit into any of the cup holders of the car, which was a little annoying during a long drive." All testers noted how easy the chug cap was to drink from.
| Capacities available | 18, 26, 36, 46, 64 ounces |
| Compatible mouthpieces | Chug cap, straw cap, cup cap, magdock, hotshot |
| Material | Double-wall, vacuum insulated, stainless steel |
| Dishwasher-safe | Yes |
Pros
- Retained temperature very well in Lab testing
- Lightweight and slim design
- Can fit in car cup holders and backpack pockets
Cons
- Dented during Lab testing
- Narrow mouth won't fit standard ice cubes
Our consumer testers appreciated how slim this bottle is, fitting into most backpacks, side pockets and car cup holders. This is the only triple-layered insulated water bottle on this list, which is impressive for how slim it is. According to S'well, the construction is supposed to keep beverages cold for 36 hours and hot for 18, and it resists any condensation from forming on the exterior of the bottles. We can confirm that it retained temperature very well. After 24 hours of temperature monitoring in the Lab, it only fluctuated by 10 degrees, which was far less than other insulated bottles we tested. It also didn't leak or spill in testing, but it did dent when we dropped it.
This bottle is available in 9-, 17- and 25-ounce sizes, and the brand often releases new colors and designs. Keep in mind, however, that you'll have to invest in a good bottle brush for this insulated water bottle since it is not dishwasher-safe and has a rather narrow mouth. (That means you may also struggle to fit ice into it, unless you have a nugget ice machine.)
| Capacities available | 9, 17, 25 ounces |
| Compatible mouthpieces | Twist-off cap |
| Material | Triple-layered, vacuum-insulated, stainless steel |
| Dishwasher-safe | No |
Pros
- Lid locks for peace of mind
- Excelled in temperature retention in Lab testing
- Easy-to-use small drinking spout
Cons
- Requires hand washing
We love that this water bottle from Zojirushi has the ease of a drinking spout and a lid that covers and protects it. The lid screws on and locks so it's great for tossing in a bag without the worry of accidental leaks. When it's time to drink, the pop-top opens with the click of a button. Keep in mind though that this water bottle isn't dishwasher-safe and requires some extra care when cleaning. Its sleek design and variety of colors are a plus, but the real wow factor is how well it keeps drinks at temperature. It excelled at temperature retention in our Lab tests; it also didn't leak or dent when we dropped it.
This versatile bottle has a small drink spout, which makes it ideal for hot beverages, but you should still always exercise caution since this bottle keeps hot beverages very hot. It's also great for keeping cold water chilled. One consumer tester shared, "I use this bottle to drink warm water and tea. I find it stays warm for a long time. I like how well it insulates. Once I forgot to bring it to work and left it in my car with hot water, and it was still warm went I came back."

| Capacities available | 12, 16, 20 ounces |
| Compatible mouthpieces | Push-botton flip top with lock |
| Material | Vacuum insulated, stainless steel |
| Dishwasher-safe | No |
Pros
- Three different mouthpiece options to choose from
- Easy to clean
- Can be turned into a filtered water bottle with an attachment
Cons
- Lid may be harder to open for some individuals
The LARQ Water Bottle is lightweight and durable with a built-in soft-touch, wide-grip handle. This model comes in three different, neutral colorways and two different capacities: 23 and 34 ounces. While this insulated water bottle is compatible with three different mouthpieces, we especially like the swig top for ease of drinking. The lid is leak-proof, but it doesn't open with a button — just manually — so it might be harder to open for some. In our Lab testing, this bottle retained temperature well and didn't dent when dropped.
This one is conveniently dishwasher-safe (unlike many of our other picks), but it's easy to hand-wash as well. Add LARQ's filter straw attachment to upgrade this pick to a filtered water bottle.

Owala FreeSip Insulated Stainless Steel Water Bottle with Straw
Owala FreeSip Insulated Stainless Steel Water Bottle with Straw
Pros
- Numerous fun and neutral color options
- Leak-proof design
- Unique hybrid drinking spout
Cons
- The handle is narrow and not very comfortable to carry
The Owala FreeSip comes in a variety of different colorways (with both multicolored and neutral options). It also comes in 24-, 32- and 40-ounce capacities, and there's even a 16-ounce kids' line. What makes this bottle especially versatile is how there are two ways to drink from it: Use the FreeSip spout as a built-in straw, or tilt the water bottle back to drink from the spout opening.
We especially like that the locking push-button lid ensures that the water bottle doesn't leak, which we proved in our Lab. The plastic mouthpiece is dishwasher safe, but it's recommended that you hand-wash the rest of the bottle to preserve the vibrant powder coat finish. The strap that keeps the mouthpiece closed also doubles as a handle for carrying, but one consumer tester did note that the handle is narrow and isn't as comfortable to carry as other water bottles.
| Capacities available | 16, 24, 32, 40 ounces |
| Compatible mouthpieces | FreeSip spout |
| Material | Double-wall insulated, stainless steel |
| Dishwasher-safe | Mouthpiece only |
Pros
- Slim, lightweight design
- Didn't leak and retained temperature in Lab tests
- Perforated handle
Cons
- There were a few small dents on the bottle after drop testing
Hydro Flask's 21-ounce Trail Series water bottle is slim and noticeably lightweight with walls that are made of thinner stainless steel than competitors. It has a perforated handle, which makes it lighter and easier to carry on long treks. It's a great insulated choice for taking on the go whether you are hiking, camping or traveling.
This bottle comes in a few different colorways and 21- and 24-ounce sizes. If you are looking for a larger water bottle, the brand offers the Hydro Flask Wide Mouth Trail bottles in 32- and 40-ounce sizes. Keep in mind that Hydro Flask recommends that you hand wash all of its water bottles. In our Lab tests, this bottle didn't leak and retained temperature well, but it gained a few small dents in our drop test.

How we test insulated water bottles
In the Good Housekeeping Institute Kitchen Appliances and Innovation Lab, we evaluate each water bottle for ease of use, performance and durability. We've tested countless water bottles over the years, and in our latest round, we tested 37 insulated water bottles side-by-side to evaluate performance and ease of use.
When we evaluate performance, we test how well they retain temperature and whether they are leak-proof. Pictured here is our drop-tester machine with dyed water that leaked out of a poorly performing water bottle.
To test whether a bottle will leak, we fill each water bottle with the same amount of water and food dye. We knock over each water bottle and let it sit on its side for 30 minutes, then check to see if any water seeps through. We also shake each water bottle at full capacity to see if any water escapes.
When it comes to insulated water bottles we evaluate each water bottle to see how well they can retain temperatures. We fill every bottle to maximum capacity with water and then remove a specific amount of water from each bottle, replacing it with a calculated amount of ice. Then the internal water temperature of each bottle is documented multiple times over 24 hours to determine which bottles retain temperature best.
To test durability, we use our drop tester machine. We drop water bottles three times each from a height of 5 feet and note any damage that occurs.
To evaluate ease of use, we consider how each bottle opens and closes. Using either a dishwasher or dish soap and a brush, we test how easy it is to clean each water bottle.
In addition to Lab tests, we send water bottles to consumer testers to get their opinions on how water bottles fare in real life.
What to look for when buying the best insulated water bottle
✔️ Material: The primary material for insulated water bottles is stainless steel. Stainless steel is relatively lightweight and great for keeping hot beverages hot and cold beverages cold, but it's not always dishwasher-safe. Most high-performing insulated water bottles are either double-wall or triple-wall insulated which helps retain temperature through additional layers of stainless steel.
✔️ Size: Insulated water bottles come in a variety of sizes, even within each model. They can be as small as 12 ounces, which is perfect for a child or for fitting into a small bag. They can also be as large as a gallon, which is convenient for a picnic with friends or long car rides. A common everyday size for an insulated water bottle is around 24 ounces (which is a size we commonly test). It's small enough to fit in a backpack but large enough that you don’t need to refill often. The larger the water bottle, the wider it likely is, so it's less likely to fit in cupholders.
✔️ Drinking spout: There is a drinking spout for everyone, and some brands even offer multiple drinking spouts to appeal to different customers.
- There are insulated water bottles with wide mouths which are great for big gulps of water but are more prone to spilling if you're not careful.
- Small mouths like sipping spouts might offer less water flow, but there is less chance of spilling and they're often good for hot beverages.
- Chug caps or larger spouts are great if you prefer to drink quickly without making a mess.
- And a bottle with a straw is helpful when you’re on the go or working out.
- There are even newer hybrid drinking spouts like with the Owala FreeSip where you can sip upright through the built-in straw, or tilt the water bottle back to drink from the spout opening.
✔️ Additional features: Some bottles feature handles for carrying around, non-slip sleeves so bottles stay put on countertops or remain in your hands even when sweaty and an additional larger bottle opening for easier cleaning or filling bottles with ice.
What is the best insulated water bottle?
When it came to determining the best insulated water bottles on the market, we collected and evaluated hundreds of data points across several different tests. While we only feature water bottles that performed well, our top performers were from Stanley, Yeti, S'well and Zojirushi. These water bottles outperformed the others — retaining temperature, not leaking and offering great ease of use. They were also popular among our consumer testers.
How do you clean an insulated water bottle?
All water bottles should be cleaned regularly to eliminate bacteria and prevent mold growth. If a water bottle must be hand-washed, look for one with a wide mouth and fewer parts, and use a bottle brush to thoroughly clean the interior with soap and warm water. If a bottle has a straw, we recommend that you hand-wash it for a thorough clean, even if the bottle states that it is dishwasher-safe.
If you're not a fan of using a bottle brush to clean an insulated water bottle, ensure that it’s dishwasher-safe before purchasing. The dishwasher's tough environment can deform the seal on bottles that aren't dishwasher safe and ruin the exterior over time, so always check if a bottle is dishwasher-safe.
