Ahead, we’ll take a look at our selections for the best insulated water bottles we could find. We also included a helpful buyers guide that can point you in the right direction – depending on your activity.

How We Created Our Rankings

We always aim to achieve accuracy when developing our product rankings. Deciding which water bottle is the best takes a bit more care than some other products since your intended use for the water bottle will play a role.

Those who are using the insulated water bottle to keep iced coffee cold on a car ride probably won’t have the same needs as someone who spends three days hiking in the mountains. We tried to create a ranking system that would work across the board, but nothing is ever perfect.

In this section, we’ve included some of the qualifications we considered for each water bottle we reviewed. That way, you can get a better understanding of our ranking system, and why one water bottle ranked higher than another.

It’s important to note that we do not receive any financial compensation from these companies. We are ranking these water bottles purely for user knowledge, which means providing accurate information is our primary goal. Money does not persuade us to rank one bottle higher than another.


Durability is one of the most important characteristics to look for in an insulated water bottle. These bottles need to endure some drops and bumps without cracking, which isn’t an incredibly high bar to reach.

One of the places where some low-quality bottles fail is in their ability to prevent leaks. Those who are hiking or camping need to keep their water inside their bottle more than most. Not only will a leaking bottle mean you’re losing water, but it also means your gear is probably getting wet in the process.

The cap quality is another place we scrutinized. Most insulated water bottles have durable frames, but plastic caps can break after a drop or two, leading to spillage in your backpack.

The name of the game with insulated water bottles is keeping your liquid cold or warm. You’ll want your hot coffee or hot chocolate to stay hot, and your cold water or sports drink to remain cool.

Insulation is one of the most important characteristics we considered when developing our rankings. If the bottle doesn’t provide sufficient insulation, then what’s the point of using an insulated water bottle.

All of the products on this list provide substantial insulation for your drinks.

User Reviews

We always take user reviews into account when developing our rankings. Since customers who purchased these products have used them in practical situations, they can often tell us a lot about how they perform.

We’re able to test these water bottles to a degree, but those who are taking them on weekend expeditions have firsthand experience of their strengths and weaknesses.

These user reviews can also tell us how these water bottles hold up over time. Using them for months and years will result in wear and tear that is difficult to replicate in a controlled setting. If the water bottle starts to degrade after a few months, we want to know about it.

Top 5 Insulated Water Bottles

1. MiiR Vacuum Insulated Bottle

MiiR, Insulated Narrow Mouth Bottle, Black, 23 Oz
  • Construction: best in class Thermo 3D Double Wall vacuum insulation eliminates condensation and keeps hot stuff hot &...
  • Materials: High quality 18/8 Medical grade stainless steel is safe & strong and won't transfer flavor or leave a...
  • Lid: easy twist, leak proof lid with functional handle. Top rack dishwasher safe.

The MiiR Vacuum Insulated Bottle tops off our list of isolated water bottles – mainly because of its durability and design. It can keep your water cold for up to 25 hours, which is the best time you’ll find from any insulated water brand.

The bottle is durable and secure, with the lid made from the same material as the rest of the bottle. This is especially noteworthy because the lid of the water bottle is the most vulnerable part. A lot of other bottles use plastic lids, which are more likely to crack and leak after repeated use.

The design is what really stands out from the MiiR bottle. While other insulated bottles are bulky, this one is sleek and easy to store bikers and hikers with limited room can use this insulated bottle to keep their water cold on their trips.

Rating: 5/5

2. Bear Grylls Triple Wall Vacuum Insulated Water Bottle

Bear Grylls Triple Wall Vacuum Insulated Water Bottle for 12 Hours Hot...
  • 12 HOURS HOT / 24 HOURS COLD. Peak insulating performance thanks to innovative triple walled design
  • 20% LIGHTER than competitors! Bottle weighs just 12.7 oz (360 g) so it’ll never slow you down
  • NO SWEAT, NO LEAKS. BPA-Free, Leak-Proof Lid and vacuum insulation technology means all liquid stays inside your...

The Bear Grylls Triple Wall Vacuum Insulated Water Bottle boasts that it will keep your drink hot for up to 12 hours and cold for up to 24, which is some of the best insulation you’ll find. There isn’t a more popular name in survival than Bear Grylls either, which adds another layer of validity to this water bottle.

Not only is this bottle durable, but it’s lightweight as well. The bottle weighs 9.6 ounces, which is inconsequential for most hikers and backpackers. The Bear Grylls line is so confident that the bottle will last that they offer a lifetime warranty on each. If the lid cracks or you start to find a leak – which we didn’t notice – you can get a replacement for free.

While the bottle’s construction is sound, we have seen some reports of the lid durability failing after multiple uses. These customers reviews seem to be the minority of cases, but it was enough for us to downgrade the Bear Grylls from our top spot.

Rating: 4.5/5

3. Thermos Vacuum Insulated 18 Ounce Stainless Steel Hydration Bottle

Thermos Vacuum Insulated 18 Ounce Stainless Steel Hydration Bottle,...
  • 18-ounce hydration bottle with durable stainless steel interior and exterior
  • Flip-top lid with built-in sipping design; button activated lid and additional clasp for secure travel
  • Thermos patented vacuum insulation locks in temperature to preserve flavor and freshness

Thermos is one of the most recognizable names in the water bottle industry, and they’ve been making durable, insulated bottles for decades. This version of the water bottle is ideal for hiking and camping, with a push release that allows you to get at your water when you need it.

The Thermos bottle comes in multiple colors and will keep your liquid cool or hot for a considerable amount of time. It’s also dishwasher safe, so everyday use isn’t out of the question with this water bottle.

The push-to-release lid presents a bit of a durability issue, unfortunately. In our experience, we’ve found that these types of lids tend to break down over time faster than others, but this bottle is still great for most uses.

Rating: 4/5

4. YETI Rambler 26oz Vacuum Insulated Stainless Steel Bottle

The YETI Rambler 26oz Vac​​​​uum Insulated Stainless Steel Bottle is one of the most durable insulated water bottles we’ve seen, which is great for those who need a bottle that can handle the rough and tumble wilderness retreats.

The Yeti Rambler is also sweatproof, which is essential for cold-weather hikes. It will keep your water from freezing inside and keep your fingers from sticking to the stainless steel exterior.

Of course, durability often comes with the downside of bulkiness. This bottle won’t be the best for universal use, but those who are taking it on cold-weather expeditions should be happy with what they find.

Rating: 4/5

5. Simple Modern Summit Water Bottle

Simple Modern Summit Water Bottle is an affordable option that offers a fair bit of versatility. It isn’t the most durable on the list, but it will keep drinks cold for 24 hours and hot for 12 – the same as the top options.

Simple Modern Summit Water Bottle is also slim and easy to pack. You can attach it to a bike or bring it to work to keep your coffee hot all day. Hikers and backpackers will have some better options, but Cayman Fitness is still a good choice for a lot of uses.

Buyer’s Guide

Now that we’ve shown you our top five insulated water bottle selections, it’s time to give you some advice on buying your own.

There are several different ways you can use one of these bottles. Hiking, camping, jogging, and everyday use require different specifications.  You’ll have to take these things into account before deciding which insulated water bottle is the best for you.

Take a look at a few of the considerations we listed below. Decide what you want to use your water bottle for, and you’ll be in a good place to choose the best option for your intended activity.

Since you can use these bottles for a variety of applications, the best insulated water bottle for one person might not be the best for another. Size is one of the variables you’ll have to think about when considering your use for the insulated water bottle you buy.

Backpackers and hikers who will be on the trail for a long time probably want the biggest water bottle they can fit in their pack. There are some size and weight constraints here as well, but having enough water for the trip is the first – and more important – concern. These water bottles usually attach the hiker’s pack in some fashion, so they don’t get in the way and hinder movement.

Runners, on the other hand, can’t use a maximum capacity water bottle on their runs. The best insulated water bottle for runners will likely be a smaller bottle, that might even contain half the water than that of the hiker’s.

Size and weight is something you’re going to have to think about before you buy. You may not care about weight and want the highest capacity available, or be willing to sacrifice some water for a lightweight alternative.


The portability of the water bottle is similar to the consideration we mentioned above. Those who are just using the water bottle as a way to save money and waste on bottled water won’t care too much about straps and clips, but those who are bringing the insulated water bottle with them on a trip will.

Some of the bottles you’ll find come with a shoulder strap. These are great for hiking, and make it easy to stop and take a sip when you need to. Runners, on the other hand, will want something that can attach to their running gear or fit comfortably in their hand. Shoulder straps just get in the way for runners and bikers.

The way you carry your water bottle will be another activity-based consideration you need to make. Again, the best insulated water bottle isn’t necessarily universal.

Opening Type

The opening type you prefer will also dictate the best insulated water bottle for you. There are several options out there, and none are inherently better than another. It all comes down to what you prefer and what you’re going to be using your water bottle for. 

Nozzles are relatively popular with insulated water bottles, and they have their pluses and minuses. They limit the amount of sloshing and splashing of the water inside, but they can also be difficult to get at when you want a refreshing sip. If you’re on a run, for instance, you’ll have to fiddle with the nozzle before getting a sip.

These nozzles often have pressure releases like inflatable tubes as well, making you bit down on them before any water comes out. This can be tough if you’re out of breath.

Screw tops are the other popular option, and they come in a range of opening sizes. You can find some with wide mouths and some with narrow mouths, and these are great for getting water in a hurry. You can also use these bottles as filtration bottles if you need fresh water in the wilderness. Make sure you buy a screw top bottle that attaches the top to the bottle itself, so you don’t lose it.
