An insulated water bottle that keeps your beverages close and cold is a great way to hydrate more and reduce your single-use plastic waste. Unfortunately, it’s hard to tell which bottle lives up to its ice-retaining claims or has an annoying lid before you’ve purchased one and taken it out into the field. So I’ve done some side-by-side testing of the top models to help you decide which water bottle you’ll cover in stickers and carry around everywhere and which would be relegated to the back of your cabinet.

First, I tested the best insulated water bottles for how long they will keep your beverage cold. I did this by filling each with the same amount of ice. Some bottles, like the LifeStraw GoSeries and CamelBak MultiBev, couldn’t hold as much ice as the others, so, in the spirit of fairness, each received five large ice cubes. Then I filled them with cold tap water and took the internal temperature of each bottle. I continued to do this every two hours for 10 hours. Then I checked the temperatures after 26 hours.
The ice water test helps to show how effective each bottle is at retaining cold. But it isn’t exact by any means. Because the insulated water bottles I tested differ in size, the higher water to ice ratio in the larger bottles mean they didn’t hold ice as long as they could have had they been filled with ice. This test simply provides empirical data to answer the pragmatic question: How long will this insulated water bottle actually keep my ice water cold?
But the mechanics of the bottle are also important. So I drank from them all and noted their caps, handles, and locking mechanisms. Read on to find a full review of each model. Check back as I continue to test the best insulated water bottles from additional brands.
The CamelBak MultiBev is a unique, multi-use insulated bottle. There’s a screw-off cup with a corresponding lid conveniently stored in the bottle’s cap. It can insulate hot and cold beverages. Drinks will stay cold for 24 hours and stay hot for 16. In the ice water test, the MultiBev blew other models out of the water. There was still some ice after 26 hours and it read some of the coldest temperatures throughout the testing period.
This bottle is great for camping because of its versatility. Start with coffee in the morning, switch to water for the day, and wind down with some wine without lugging a hazardous glass bottle into the backcountry. It’s actually 3 ounces short of a full wine bottle, but leaving half a glass behind isn’t the end of the world. Plus, it’s ideal for sharing. Give a friend the cup and enjoy the rest of your beverage from the bottle.
The outside features a matte finish that doesn’t sweat or slip and the silicone base makes it harder to tip over. All parts of the bottle are dishwasher safe. At $52, it might seem expensive for a water bottle, but when you take into account that you’re getting a 16-ounce tumbler ($22) and 22-ounce water bottle ($32) together in a convenient package, the price makes sense.
I’m happy to carry this 1 pound, 7 ounce bottle on a day hike in exchange for a convenient and chilled beverage. If you use this as your daily water bottle, you always have a reusable cup handy for coffee runs, at the expense of lugging around the heaviest bottle on this list. One issue is that the bottom of the bottle narrows to accommodate the screwed-on cup which limits the space for ice if you use large cubes.
The Rtic insulated water bottle is comfortable to hold and drink from. The lid doesn’t leak and the exterior doesn’t sweat. The mouth opening is perfect to take a long swig with no spills. The handle feels sturdy and I trust its structural integrity to carry the bottle when full. You can keep beverages hot or cold, but the only claim Rtic makes is that it can hold ice for up to 24 hours. During the ice water test, the bottle stayed chilled for the duration of the 10 hour test period. After 26 hours, it was only 2.5 degrees warmer than the initial temperature. The ice, however, had melted. I attribute that to the higher water to ice ratio than the smaller bottles.
The large 32-ounce capacity is great for all-day hydration though the bottle is too large for most cupholders. At such an affordable price and excellent chilling performance, this is the best value insulated water bottle.
Typically, the weight of my water bottle means a lot to me. I don’t want to lug something heavy along on a hike for a small luxury like chilled water. But, I was surprised at how light the empty HydroFlask Trail was. HydroFlask claims your water will stay chilled for 24 hours and hot beverages will stay warm for 12 hours. During the ice water test, the 32-ounce Trail Series was comparable to the best value winner, Rtic. At the 26 hour mark, the Trail Series was only 3.4 degrees warmer than the starting temperature. The Rtic marginally beat HydroFlask for cold retention. The Trail Series is a few ounces lighter and skinnier for the same capacity as the Rtic, though double the price. The Trail Series is 3.2 inches in diameter which is slightly too large for standard cupholders.
I brought this bottle car camping for the weekend and it has already sustained a few scratches and dings. While I’m far from precious with my water bottles, be prepared for some added character in the form of silver stainless steel peeking through your chosen color. Hydroflask does offer a trade-in program where you can send in your old water bottle for proper recycling and receive a $5 credit for your next one. That makes it the best reusable water bottle because you can recycle it and reuse your credit. Overall, this bottle has great insulation properties with a reduced weight. The carry handle is convenient to loop or clip to your bag, and the wide open mouth is great for people uninterested in bothering with straws, spouts, or locks.
While OtterBox doesn’t explicitly make any numerical claims as to how long your drink will stay cold, it does feature a copper lining designed to keep your drink at the “perfect temperature.” OtterBox told me that the copper’s conductive properties stabilize the thermal loss, ultimately maintaining your drink’s temperature whether it’s hot or cold. During the ice water test, all of the stainless steel models dropped in temperature over the first six hours while the ice chilled the water around it. The Sport water bottle dropped the most in temperature at 5.6 degrees cooler than the initial temp. By the next day, it was only 4.1 degrees warmer.
You can drink out of the Sport with a straw or spout, just remove the straw and O-ring insert. However, when tipping the water back for drinking out of the spout, water can escape through the air hole. The short and fat spout makes an odd mouth piece for sucking out of the straw. The cap that covers the spout is connected to the water bottle. This is great for not losing parts, but it does make opening and closing more annoying. And you can’t fully remove the lid from the bottle without first opening the cap.
This insulated water bottle includes a dual filter system inside. The carbon filter reduces chlorine, odors, and organic chemical matter for improved taste. This filter lasts up to 26 gallons or about two months. Further, the membrane microfilter protects against bacteria (including E.coli and salmonella), parasites, microplastics, sand, dirt, and cloudiness. The membrane microfilter lasts up to 1,000 gallons, about five years of daily use. LifeStraw says this system is good for contaminated water sources or simply providing a better taste, making it great for travel.
In the ice water test, the GoSeries was 12.4 degrees warmer after 26 hours. This was the worst performance of the stainless steel models. But, after 10 hours it was only 3.3 degrees warmer. So just bank on this one lasting for a work day. While LifeStraw’s fresh and clean water is tempting, the nozzle creates an odd drinking experience. You have to suck on the small spout to get water out, but the mouthpiece feels too short and square for a comfortable drinking experience. I’m sure you could get over this for a vacation, but maybe not for everyday use.
While I wasn’t able to put the Philips Go Zero through the ice water test, staff writer Laura Lancaster named it the best insulated bottle in her test of the best filtered water bottles. She says, “If your primary reason for wanting a filtered water bottle is to have great tasting water, the Philips Go Zero is a smart choice. Not only does it remove chlorine and particulates from water, ensuring it will taste great, but it’s also insulated, so your cold water will stay cold longer. Just keep in mind that this filter is not the right choice if you are concerned about the safety of your water, as it doesn’t remove bacteria, protozoa, viruses, lead, PFAS, or other dangerous chemicals.”
The CamelBak Podium isn’t stainless steel, but it’s still an insulated water bottle. The double-wall construction lined with a thin polyethylene foam sheet is designed to keep your water cold twice as long as a non-insulated bottle. In my ice water test, the Podium was the first to lose all its ice in four hours. After six hours it was 15 degrees warmer than its initial temp. But, your uninsulated cup of ice water would likely melt in two hours so I believe CamelBak’s claims.
This bottle is lightweight, easy to drink from, and doesn’t spill when the cap is locked. It’s designed to fit inside various bottle cages, but the size is perfect for fitting into the best hiking fanny packs such as the CamelBak M.U.L.E. 5 Waist Pack that won best for hydration. It fits into most cupholders, too. There’s no handle, but the ergonomic shape makes it easy to grab and go, whether you’re cycling, hiking, or hanging around town.
If you’re purchasing an insulated water bottle, you likely want your water to stay, well, insulated. In my ice water test, I put these bottles to the test. Pay attention to the leaders if you want to enjoy chilled water all day long.
There are different caps with different drinking features for all of the best insulated water bottles. If this is your everyday water bottle, you’ll be using it all the time so it’s best to pick one you enjoy drinking out of. If it’s too much of a pain to use or unscrew, it might become a paper weight on your desk instead.
The no-name water bottles you find on Amazon typically suffer heaviest in one category: durability. All of the insulated water bottles on this list are from reputable brands and were tested for leaks.
