Insulated water bottles are an essential gear item for summer — that much is obvious. But they also have lots of great uses throughout the year. Check out the best insulated bottles of 2020 here.
If you’re looking to purchase a water bottle for outdoor adventures, an insulated bottle should be high on your list. Insulated bottles are designed to keep cold liquids colder longer (and hot liquids hotter), and are usually higher-quality and more durable than their plastic counterparts. Plus, having a reusable water bottle is great for the environment. Read on to find the best insulated water bottles on the market.
For this review, we looked at water bottles that have some form of insulation (whether ceramic or stainless steel construction) and a good-sealing cap or lid. And we evaluated each on factors like insulation, shape and volume, durability, and price. Then we checked each brand’s bottle performance through online reviews across multiple platforms.
To choose the best of the best, we ranked each bottle on features, feedback from our testing, the volume of positive reviews and feedback, and price. Scroll through our picks for the best insulated water bottles of 2020 or jump to a category below:
Best Insulated Water Bottles
Best Overall: Hydro Flask Standard Mouth Bottle 24oz.
Sometimes you don’t want to mess with the OG. Hydro Flask’s Standard Mouth bottle ($35) won out as the best insulated bottle, with an overall 4.61-star rating across a massive 13,000 reviews.
The brand’s double-wall vacuum insulation and pro-grade stainless steel are designed to maintain drink temperatures for hours without altering taste, and we found during testing that this bottle is pretty durable as well. As one reviewer put it, the Standard Mouth can really take a beating and still work great.
Reviewers rave about this bottle for its great insulation and lineup of more than 10 fun colors. Also, being on the skinnier side, it fits in most cupholders and pack pockets. While it comes in 18- and 21-ounce sizes, we like the 24-ounce best for most activities.
Why you should buy: We’ve hiked with it for days, left it in hot cars for hours, and used it from office to trail. Plus, Hydro Flask offers a lifetime warranty.
Runner-Up: YETI Rambler Chug Water Bottle 18oz.
YETI’s 18-ounce Rambler Bottle ($35) is another amazing insulated bottle. This one tied with our top choice for its stainless steel construction, insulating performance, and price. However, it weighs slightly more — although that also gives it points for durability.
The cap style, its ease of drinking, and protection against leaks was the only controversial feedback amongst testers — some love the cap, some don’t. That’s about it.
Why you should buy: This bottle had the most 5-star ratings out of all the ones we tested and is a super-solid choice for the price. It was also in our top three for most durable (in terms of deterring dents and dings and overall longevity).
Best Budget: GSI Outdoors Microlite 500 Insulated Bottle
GSI Outdoors dedicates an entire section of its website to all things insulated. But the best insulated bottle the brand makes, in our opinion, is the Microlite 500. (The 500 refers to 500mL, but it also comes in a 750mL/24-ounce size.) In addition to performing great in testing, this bottle is one of the lightest insulated stainless steel bottles on the market at a little under 8 ounces.
The Microlite 500 ($26) is also our “best for hot contents” choice — it really lives up to that leakproof level we all search for. We don’t have quantitative proof, but hot liquids stay really hot in this bottle, and we mean piping hot. Reviewers agree. (And the cold stuff stays cold too if you were wondering.)
The flip cap — while it does have a little bit more complicated construction — is also really wonderful for travel, and we believe it’s a really nice feature. And the lock feature works well; it doesn’t accidentally pop open and spill contents when this bottle is in your pack. One thing we will note, though, is that you’ll want to wash the interior cap thoroughly between uses and drinks.
Why you should buy: In short, contents stay very hot or very cold, and the price is right.
Best of the Rest
We decided not to choose any bottle as the most durable or most versatile because all of the insulated bottles below performed great and proved plenty durable — both during daily use and out on the trail.
If you’re looking for something different (whether in cap style, size, or color) from our top three above, check out these bottles below.
This bottle has a unique cap design but still functions great. The cap is a screw cap that flips open to attach to a magnet out of the way.
If you’re a multitasker and want a bottle with easy one-handed opening and no chance of losing your cap, this bottle might be for you. (Bonus: It’s a universal cap that fits a slew of other CamelBak bottles.) Despite the cap design, this bottle is on the lighter side, and we found it to be very durable, especially when traveling.
The CamelBak Chute Mag ($30) has 18/8 grade stainless steel construction with a BPA-free magnetic cap. Reviewers love how cold ice and water stay in this bottle, but some commented that it’s prone to leaking.
Why you should buy: The volume for the price point makes this a super-great investment.
The bottle boasts it will keep contents cold for over 14 hours thanks to its smooth interior ceramic construction (as opposed to stainless steel). This classic bottle has over 4 stars. It has a silicone footpad and is BPA-free and dishwasher-safe. Stanley also offers a lifetime guarantee with the GO Vacuum Bottle ($35).
Why you should buy: If you don’t mind carrying a bottle that’s slightly heavier than most, and don’t want a stainless steel interior, go for this Stanley vacuum bottle.
Hydro Flask’s new Lightweight Trail Series bottles have really won us over. If it weren’t for the price, this bottle might be in our top three.
The Lightweight Wide Mouth ($45) weighs just 10 ounces, has a perforated strap to keep weight down, and is designed to work with most backcountry water filters. It’s also gotten super-high reviews (over 4.9 stars on Hydro Flask’s site) since its launch.
Why you should buy: If you want to invest in a Hydro Flask, this is the best lightweight option.
This Klean Kanteen bottle ($40) has a wide mouth, is vacuum-insulated, and holds 32 ounces of your drink of choice. It’s more expensive than others on this list but has everything you need: a cap and fold-down carry handle, a stainless steel interior, and insulation to keep liquids cold or hot for over 20 hours.
Some testers commented that they don’t like the lid design, and it’s not dishwasher-safe. We noted that it’s slightly narrower and shorter than other wide-mouths on this list.
Why you should buy: This Klean Kanteen is very durable and also has a bunch of interchangeable cap options.
Hydro Flask made a pretty awesome solution to those who don’t like the style of a wide-mouth bottle (but want something with lots of volume): a straw drinking lid.
This 32-ounce bottle has the same stainless steel, double-wall vacuum insulation as the standard Hydro Flask bottle but measures slightly wider and has the option of a straw lid. But at $50, it’s definitely an investment.
Reviewers noted that this bottle is great at keeping water cold for at least 24 hours and holds up really well to daily use.
Why you should buy: If you want something durable and with more volume, get this Hydro Flask.
Purist uses a glass interior to combat the odors and flavors some don’t like in their stainless steel bottles. Meanwhile, the exterior sports the tried-and-true stainless steel construction for durability. The brand’s smallest size, the Maker 10 oz. bottle ($50), has a convenient sipping cap.
We also liked testing the 32-ounce, wide-mouth size (same insulation and materials, just holds more), although the 18-ounce fits much better in cupholders, packs, and bags. We like the muted colors and professional aesthetic of this brand.
Why you should buy: If you can’t stand the aftertaste of stainless steel, go for this sleek glass-insulated bottle instead.
CamelBak MultiBev 12 and 17oz. & 16 and 22oz.
This is by no means a bottle you’ll want to take backpacking, but it’s a really cool design. CamelBak designed the MultiBev ($48-50) for just what it sounds like — multiple beverages on the go.
It’s great to fill up with water or coffee at the start of your day, and then have a reusable and insulated option for other drinks later. The incorporated cup is also great for sharing, and both components hold the cold and hot temps well.
However, it’s heavier and pricier than most.
Why you should buy: If you want something really versatile and great for travel and don’t mind paying a higher price, this CamelBak bottle is for you.
Like YETI, ORCA also makes durable, insulated coolers for the outdoors and drinkware with the same insulation to match. The ORCA Hydra ($30) has 18/8 grade stainless steel double-wall construction with a super-grippy carry handle.
We found its insulation to perform about as well as a Hydro Flask in keeping water cold. Really, if you like the look of this bottle, go for it — it’s also got a great price tag.
Why you should buy: Get the Hydra if you like bold colors and want to support a small(er) business.
CamelBak’s Podium Chill Bottle ($16) has more reviews and higher ratings than Polar, one of the first plastic insulated bottle brands on the market, which is big. The Podium Chill has an overall 4-plus-star rating across nearly 3,500 reviews. It comes in 21- and 24-ounce bike cage-compatible sizes and has a twist lock jet valve to prevent spills.
Reviewers used to have lots of problems with the valve and cap, but CamelBak has recently redesigned that feature. This is a great bottle for rides (it’s also one of the narrowest insulated bottles we could find).
Why you should buy: If you want an insulated bottle that works outside for under $20, grab the Podium Chill.
This is the only one of two bottles on our list that isn’t made with double-wall stainless steel for insulation. Like the CamelBak Podium Chill, Specialized’s plastic insulated bottle ($20) uses a BPA-free plastic insulating barrier to keep contents cold. This bottle also comes with a fantastic price point and doesn’t require unscrewing or opening any sort of cap.
Why you should buy: If you want something that’s insulated, has an easy-squeeze feature, and will fit in a bike cage, get this Specialized bottle.
How to Choose an Insulated Water Bottle
Pick a water bottle with enough volume for all your activities. If you really love one particular insulated bottle, consider getting two sizes — one for daily use and one with more volume for longer trips or travel. (And also consider if the bottle you’ve chosen will work with a water filter or in your pack pocket if you know you’ll be taking it with you on the trail.)
Make sure the bottle you choose lists how long it keeps water (or other liquids) cold. The standard is 24 hours, but we’ve noticed in many of these bottles the contents will stay colder for longer. You’ll want to know how good the insulation is, especially if you live in a hotter climate.
Another decision you should make when choosing between bottles is what type of mouth you want. Do you want narrow for easy drinking, or wider to fit in a water filter? Do you want options for interchangeable caps? All these are things to consider.
What are the interior and exterior materials? Most insulated bottles use some form of stainless steel double-wall insulation, but not all. Also look at the exterior material: Is there a powder coating? Does it reduce condensation? Is there a rubber grip or protective design on the base?
Once you find a bottle you think will work for you, pick out a fun color while you’re at it! Colors are mainly just a preference but can also help identify your bottle in a crowd.
Lastly, think hard about your budget. These bottles are an investment but totally worth it, especially if, like us, you spend lots of time outside. And before buying, always check to see if your favorite bottle is on sale.
That’s it! Go forth, hydrate, and have fun!
