Insulated Water Bottle Buyer’s Guide

What Is A Insulated Water Bottle?

You’ve probably hear the term “insulated”, “double wall” or “vacuum” when comparing the best insulated water bottles. So, what exactly does it mean for a water bottle to be “insulated”?

In the most basic terms, an insulated water bottle just keeps heat transfer from the water bottles contents to the outside environment. This means keeping a warm liquid hot or a cold liquid cooler for longer. This is ideal when you are enjoying drinks in particularly hot or cold climates—the last think you want is your morning coffee to get cold just after some minutes when outside in the cold!

In insulated water bottles this is achieve by creating a void space of air with a design called Double-Walled Vacuum Insulation. This may ring a bell, as it what the classic Thermos products used back in the day. Now there are tons of manufactures putting this practical design to use with an assortment of great water bottle products.

Why You Need An Insulated Water Bottle

If you’re into your third hour of traveling through the bustling streets of India in a less than average “taxi” without air con, your insulated water bottle becomes an absolute savior.

With your mouth dry as a dessert and sweat beading down your forehead, a sip of that icy goodness will bring ten times the relief than that of a warm plastic bottle of airport water.

Some of the best brands of insulated water bottles will keep water icy up to 24 hours (some say 90hrs for cold!)- the same goes with keeping hot beverages warm for 24 hours.

There are various other benefits to buying an insulated water bottle such as:

  • Environmentally friendly- easily recycled as steel is a natural material.
  • Don’t contain the same toxic chemicals that plastic water bottles do.
  • Long lasting and durable.
  • Dishwasher safe.
  • Re-usable time and time again.
  • No plastic after taste.

Insulated Water Bottles Uses

I’m sure you have a specific use that you’ll use your insulated water bottle for, but specifically they are great for:

  • Keeping coffee, tea and other hot drinks warm while outdoors
  • Making sure your beer stays cold on a super hot day
  • Keeping white wine cool on a picnic
  • Storing hot soup for lunch while at work or on a hike
  • Always having cold water when traveling
  • Storing cold drink in your bag without having the bottle sweat

Basically anytime you want to keep a drink hot or cold, an insulated water bottle will do the job.

There are tons of great and practical uses of insulated water bottles and really no drawbacks. The biggest I can think of would be that they are a bit more bulky and heavier than you typical bottles, but the benefits you get from them is worth it in my opinion.

Once you’ve used a high-quality insulated water bottle you’ll never go back to your old water bottle.

How To Choose The Best Insulated Water Bottle

Material

The best insulated water bottles are made from food grade stainless steel. Typically you’ll find bottle made with 18/8 or 18/10 stainless steel. They should be BPA free since there is no need to have a liner inside a stainless water bottle, unlike aluminum bottles.

Stainless steel is a strong materiel and perfect for double-walled vacuum insulation bottles. It’s the most effective design to buy as the hot or cold liquid is trapped inside and stainless steel keeps the bottle strong and durable.

Size

Depending on how you plan to use your insulated water bottle you’ll need to consider what size to go with.

How far are you traveling before you need to re-fill? Will you take extra weight in your pack in order to have enough water to last?

You can find almost every size of insulated water bottle for every purpose. Most major insulated water bottle brands make several size options for each model. If you just want a small bottle for a cup of coffee a 12oz bottle could work perfect. And if you want a huge water bottle to store cold water in your car while hiking, a 40oz bottle will do the job.

Durability

Stainless steel is the ideal material for insulated water bottles. Add a powder coating on the outside and you have the perfect combination to resist dents and scratches. Plus you get some added grip with a slightly rough powder coat.

If you want to keep your weight down in your luggage or backpack, you may choose a lightweight steel insulated bottle but this will more easily take hits and dents than a heavy duty bottle.

Bottle Mouth

Insulated water bottles are available in various mouth widths. The mouth width on a water bottle just refers to how wide the opening is at the top of the steel water bottle.

Mostly this just comes down to personal preference. Consider getting a wide mouth water bottle if you like to take big sips of water or plan to add ice to your drinks. You’ll also be able to more easily scrub and clean the inside of the water bottle if the bottle has a wide mouth.

On the other hand if you want a narrower sized bottle to slip into you bag, you’ll be better off going with a narrow mouth insulated water bottle.

Handle

A handle located at the top of the bottle is great if you’re a backpacker or hiker as you can easily add a clip and attach to your backpack for convenience. You can also find the traditional fold-out thermos handle on the side of the bottle.

A handle is useful for toting around on the side of your bag or in your finger if you are cruising around without a bag. Some handles will be flexible and attached to the bottle and others will not be attached. This is an factor to consider if you tend to lose your bottle caps!

There are various handle designs out there and you’ll find ones made from plastic, wood, to metal. I’d suggest sticking with plastic or metal for durability.

Style

Straw or no straw– will you be using your bottle on-the go? If hiking or in transit then you probably want to go the inbuilt sipper style straw for convenience rather than a screw top.

Think about the width of the bottle, if you’re running you want it to be slim enough to grasp in your hand. When it comes to colors and designs you will be spoilt for choice with an endless array of bottles in every style.

How Insulated Water Bottles Work: Double-Wall Vacuum

The double wall vacuum feature is the secret to keeping liquids either cool or warm. It’s a simple and straightforward design, yet works remarkably well.

How does it work?

The liquid sits in the bottle with a double wall, being dead air space between the liquid and the outside of the bottle. Check out this diagram from Thermos to better understand how a double-walled vacuum works inside a water bottle.

The space between the two walls is vacuum (or evacuated air) which further helps any heat transfer between this gap. In general, air pockets are incredible efficient at insulating and not allowing heat transfer. This is the same concept of how a down jacket works to keep you warm.

Therefore the temperature of the liquid remains the same as when you first placed it in there- given there is nowhere for the heat to be transferred to. This is how the temperature remains more or less then same for 24 hours +. The best insulated water bottles on the market will keep your drink cool or hot at least this long.

The Bottom Line

Why have just a standard water bottle when you can step up to an insulated water bottle! Whether you’re adventuring in a hot or cold climate, you can have all bases covered with an icy cold beverage or one to warm you up after a day in the snow.

The market for insulated water bottles has exploded of late because they are unmistakably a great piece of equipment to add to your trip. Grabbing one of the best insulated water bottles from this list will be sure to keep your beverage hot or cold and become one of your ‘never leave home without it’ pieces of travel gear.
