What Is An Insulated Water Bottle?


An insulated water bottle is a portable container for liquids that can keep the proper temperature for a long time. This means you get to enjoy warm or cold liquids longer. This is achieved by having the double wall vacuum insulation that was originally used by Thermos products in the past.

Now, many manufacturers are using this innovation to design the insulated water bottles that we have today.

How Does It Work?

The science behind in keeping the proper temperature in insulated water bottles is the double wall vacuum feature. When the liquid is in the water bottle, there is dead air space between the liquid and the outer layer of the bottle.

The space between the double walls acts as an air pocket, efficiently insulating the contents of the bottle and not allowing heat to transfer inside. Therefore, it keeps the temperature the same because there is nowhere for heat to transfer to. The real insulated water bottles should have this feature to keep drinks hot or cold for a long period of time.

How To Choose A Good Insulated Water Bottle

If you want to get the best insulated water bottle, then you have to know what to look for before purchasing one.


The best insulated water bottles are made with 18/8 or food grade stainless steel. These are BPA-free and should not contain any toxic chemicals. The stainless steel material is perfect for the double-wall vacuum insulation feature and is very effective in keeping the temperature. Other than that, it makes the bottle very strong and durable.


Stainless steel is the material used for insulated water bottles and manufacturers add a powder coating on the outside which can avoid dents and scratches. These make the bottles very durable and last long. Many good tumblers are also made with the same material like the tumblers you can find here.


One thing you also have to consider is the size of the bottle that you want. How are you going to use it? Where are you bringing it? Will you put it in your bag or in your car? Water bottles have a wide range of sizes for different purposes. Some range from 12oz up to 40oz. You can also purchase more than one size if you need to.


A bottle handle can be very useful which is why it should also be a consideration. You can easily bring your bottle or attach it to your bag depending on the handle style. There are also different handle materials but it’s best to stick with plastic or metal for durability.

Bottle Mouth

Insulated water bottles come in different types of bottle mouths. The width can vary and choosing can just be based on personal preference.

A wide bottle mouth can be used if you like taking large sips or place to include ice in your drink. This size can be scrubbed and cleaned easier. However, if you want a smaller sized bottle to easily fit in your bag, then a narrow bottle mouth will work better for you.


Picking the style of your bottle can also be influenced by how you’re going to use it. Do you want it to be small or big? Are you going to use it for hiking or for work? What color and design do you want? There are many different styles to choose from and since you’ll be using your bottle a lot, it’s nice to personalize it.
