Pros & Cons

You’ve heard it before: water is life. OK, so not everyone needs to drink eight glasses of water a day — that’s a fast track to spending the entire day in the bathroom — but keeping hydrated throughout the day has many benefits.

It keeps your body flushed of waste, helps regulate your temperature, and keeps your body and joints well lubricated. But it’s good to be both practical and environmentally-minded. Single-use plastic water bottles are a major problem. The world’s population goes through about one million plastic bottles per minute. Even more alarming is the fact that less than 9% of these bottles find their way into a recycling bin after use. It's estimated that about half a trillion plastic bottles are sold around the world. 

That’s why a good reusable insulated water bottle is an excellent alternative to plastic water bottles. Here’s some need to know information.

How do insulated bottles work?

Insulated bottles — also called vacuum insulated bottles — are made with two (or even more) stainless steel walls, with a vacuum in between. This creates thermal insulation, which protects your drink against the external temperature. In other words, hot drinks stay hot and cold drinks stay cold.

How long do insulated bottles maintain a liquid's temperature?

This varies from bottle to bottle, but the best bottles promise to keep hot drinks hot for 12 hours and cold drinks cold for 24 hours — but you can find bottles that claim to hold colder temperatures for even longer than this.

Are insulated bottles dishwasher safe?

Generally, no. There are two reasons for this: because the dishwasher can erode the bottle’s powder coating, which gives the bottle its grip. Also, because the force of the dishwasher might damage the vacuum seal. A few top brands have started making insulated bottles that can go in the dishwasher, but most recommend hand wash only. It’s one of the few downsides to insulated water bottles.

What does BPA free mean?

This is something you’ll see a lot when researching bottles. One-time use plastic bottles can contain a chemical known as Bisphenol A (BPA) that can be harmful to your health. Research shows that BPA can contaminate food and drink, though research also says that low levels of BPA are safe. Still, to ensure your food and drink containers are non-toxic, choose items that do not use Bisphenol A.

Is bottled water better than tap water?

Not necessarily. Many bottling companies use the mains water supply, then triple filter it, bottle it, and then sell it. Tap water is sometimes safer to drink than bottled water because government agencies regulate the water closer and more often than some private bottling companies do. If you’re worried about the quality of tap water, simply invest in a filter to get rid of any harmful elements, such as metals and bacteria. 

What is the best insulated bottle?

You’ll have to decide that, because it’s all about what suits you and your lifestyle. But consider a few points before making a decision, because not all insulated water bottles are created equal.

Do you need something lightweight for sports or physical activities, such as hiking or camping? Or something robust that can handle being tossed about in a bag? Do you need a bottle that will save space in your already crammed luggage? Do you want a bottle with a selection of nozzles and caps? How long do you need your water to stay cold?

But don’t worry, we did the research, scoured the internet, and browsed reviews to find all the best insulated water bottles. We think you’ll want to drink to these top picks.

These are the best insulated water bottles for 2022.

Looking for a versatile water bottle that can go with you on any adventure? You can’t go wrong with the Hydro Flask(opens in a new tab) insulated water bottle. 

Its double wall vacuum insulation protects temperature for hours, keeping beverages cold for up to 24 hours, and hot up to 12 hours — no matter what the weather is outside. It’s the perfect hydration vessel, whether you’re out on the road (it fits most cup holders) or going for a run (the powder coat makes it easy to grip and keeps the bottle condensation-free).

We love that this bottle is ultra-durable — this baby is going to last a long time. It’s made of high-quality 18/8 stainless steel construction, which also ensures pure taste and no flavour contamination. Because you don’t want today’s water to taste like yesterday’s coffee, right?

We also love that the standard mouth size on this bottle is actually wide enough to make adding ice cubes easy-peasy without having to deal with spills while sipping (or guzzling) water on the go.

We all know keeping hydrated becomes even more important when you’re hitting the gym, playing sports, or enjoying outdoor activities — the more you sweat, the more you need to drink water to cover the fluid loss. Keep the CamelBak Eddy(opens in a new tab) in tow and it’s easy to keep up with the fluid intake.

This bottle features double-wall construction to keep water cold long after you start pedalling (or running, or spinning, or yoga-ing). Its self-sealing valve nozzle delivers 25% more flow — plenty to refresh and rehydrate you — with an extra safety measure: leak proof when it's closed, spill proof when it's open.

The body of the bottle has a high-quality powder coat finish, with sweat-proof insulation to keep it dry at all times.

If its name didn’t already give you a clue, this bottle is one of the best for keeping your water really cold. 

Impressed with bottles that keep water cold for 24 hours? Get this: The Coldest Water(opens in a new tab) bottle keeps water cold for up to 36 hours! Some reviewers have even reported ice cubes still frozen in the bottle after 36 hours.

This champion of water bottles is made from durable, double-wall, 18/8 stainless steel to keep drinks insulated. It also features a rubber grip for easy handling, a leak-free cap, and a sizable mouth. And don’t worry about losing it at the pool — this bottle also floats.

This bottle is heavier than most insulated water bottles, but it's the heavier construction that helps keep the temperature for longer.

  • Height: 29 cm
  • Capacity: 700 ml

This Infusion Pro(opens in a new tab) model is super easy to use, so you can have tasty fruit-flavoured water in a flash. Just unscrew the top and bottom of the bottle, place the ingredients in the fruit cage before filling the bottle with water, and let the water soak for one to two hours.

The inset strainer keeps pulp, seeds, and ice away from your mouth, so you only taste the fruit-infused water.

While the actual water bottle isn't technically insulated, the Infusion Pro comes with a neoprene sleeve to keep your drink refreshingly chilled. This also eliminates condensation, also known as bottle sweat.

The bottle features a convenient sport flip-top so you can enjoy your beverage on the go. It's also BPA-free, leak-proof, and dishwasher-safe. 

Best For Kids

  • Height: 19 cm

Kids need a good, reusable water bottle, too — especially one that’s BPA-free. Enter Klean Kanteen. The Kid Classic(opens in a new tab) water bottle has the same durability, versatility, and double-wall insulation of the grown-up Klean Kanteen Classic(opens in a new tab) water bottle.

Its smaller size is great for little hands, and its leak-proof loop cap means their backpack stays dry and free of spills and messes.

The bottle keeps beverages like hot chocolate warm for up to 12 hours, and drinks such as orange juice icy cold for up to 24 hours. The large opening also fits ice, and makes it easy to fill and pour. And just check out the roar-some tiger design.

And like its bigger Klean Kanteen counterpart, the Kid Classic is durable and great for active children (and clumsy parents). The bottle is compatible with Klean Kanteen’s classic lids.

  • Height: 23 cm
  • Capacity: 480 ml

OK, so it is not really a water bottle, but the Zojirushi vacuum mug(opens in a new tab) is the perfect portable vessel for hot drinks, so we think it deserves a mention.

The stainless steel construction also keeps beverages cold for hours. But it's the heat retention that makes this really stand out, keeping beverages at 70 degrees for up to six hours. 

The mug features a tight-fitted flip-open lid with a safety lock that makes drinking from the mug easy and prevents your morning coffee or tea from spilling, even while you’re on the go. An air vent on the mouthpiece allows liquids to flow out smoothly, without gushing or overflowing, and the lid even transforms conveniently into a cup. 

There’s more: it’s built with a nonstick coated interior (so cleaning the mug is a breeze) and all surfaces that come into contact with your drink — including the lid and 18/8 stainless steel interior — are BPA-free.
