This fact is maintained if and only if we move towards purchasing the best insulated bottle on the market. It is, therefore, appropriate to tackle small surveys before validating the purchase of the utensil.

Insulated bottle buying guide

What is an insulated water bottle?

What is commonly called a thermos is more precisely a gourd, a bottle, carboy, or even a flask with isothermal capacity. As you have seen in selecting the seven insulated bottles above, it is a transportable water container used to keep the freshness and heat of a drink at a constant level for 12 to 24 h.

Typically, these bottles use vacuum technology to maintain temperature. Design-wise, they have an inner wall separate from the outer skin to prevent heat transfer. Most often, the internal wall is doubled or tripled to optimize temperature maintenance. Reinforcement of the wall is usually done with copper insulation.

How long does the temperature hold for an insulated cylinder?

Generally, the carboys, flasks, gourds, or insulated bottles maintain freshness over 24 to 48 hours. The models for coffee, tea, herbal tea, hot water, and cold drinks show a higher cold temperature holding capacity for keeping warm for up to 12 hours. However, flagship brands like thermos promise 24-hour warming.

The ability to maintain freshness is always higher because some insulated bottles can also accommodate blocks of ice. Therefore, in summer, it is more judicious to rely on a model with a wide opening to facilitate the addition of ice cubes in the drink. In winter, fill the gourd well to optimize heat retention.

What is its purpose of use?

One of the first things to define before purchasing an insulated cylinder is its purpose of use. Do you need a coffee thermos to take to the office, or rather an insulated water bottle for yoga? In both cases, you need a light and easy transport model like the one offered by MossyOak.

If you go hiking in the snow, prioritize the model presented by Thermos. It weighs a bit heavier than the other thermos flasks shown above, but it has better heat holding capacity.

As for those who want a versatile and complete utensil, models with colander, infuser, and integrated cups must be considered. Heavy tea drinkers can already be interested in the Thermos offered by MoovTek.

Classic vacuum bottles vs. retractable vacuum bottles

Insulating bottles are available in retractable versions. The last fold into an accordion once emptied.

Thus, they take up little storage space, unlike conventional insulated bottles. They are also lighter. For hiking or camping, this type of insulating bottle is more practical.

However, it should be remembered that these shrink bottles are not as strong as conventional Thermos.

Indeed, their lifespan is estimated at around one year, a year and a half for the most robust. It is therefore only interesting to take one for a different use project.

Unconditional hikers who want to combine lightness and space-saving are often tempted to purchase these retractable insulated bottles. However, they may be disappointed by the performance of the latter.

The best in their case is, therefore, to bet on an isolated gourd of small capacity.

What type of opening to prioritize?

The opening of an insulating bottle can be done with a screw cap, suction cup cap, pump cover, or snap-on hood with a sports drinker nozzle. Each type of opening naturally determines the ease of access to the drink. It’s up to you to see what works best for you.

Classic or one-handed opening?

You will find Thermos with classic opening and others that open and close with one hand on the market.

Classic models take longer to open and close but are pretty acceptable for home or camping use.

For athletes and hikers who often have busy hands, the one-handed opening is more suitable.

Wide or narrow opening?

If you plan to drink directly from the gourd, narrow space is recommended regarding the opening’s width. Otherwise, a more comprehensive introduction with an anti-drip system is more practical.

Do you need to keep warm and cold at the same time?

Insulated bottles are more expensive than traditional gourds. However, if you want a single container to meet your all-season homemade beverage needs, you’ll need an insulated gourd. For those who only need to carry a cold drink to hydrate themselves at the gym, the classic water bottle is cheaper.

Are you reluctant or unwilling to drink from a plastic container?

More than one brand offers plastic insulating cylinders on the market. As this material is cheap, it meets the demand of a wider audience. However, plastic is increasingly boycotted due to its unsuitability for food uses. If you are reluctant to use a plastic container for your needs, your concerns are legitimate.

Be that as it may, the agri-food industry has evolved thanks to the various research carried out by scientists in the field. Today, we find plastic-free BPA. It turns out that this type of plastic is utterly harmless to health. So if you want a lightweight insulated container for your drinks, you can always go for the BPA-free plastic models.

Is it interesting to take several insulated bottles?

Indeed, it is interesting to take more than one insulating carboy to store your different drinks. However, to avoid unnecessary expense, pay attention to the value for money, convenience, and durability of each cylinder.

The design materials of these bottles

To make the best choice in terms of an insulated bottle, you have to look at the material, among other things. Here are the things to know about it:


Several opinions attest to the harmfulness of plastic. However, plastic is a good insulator and is lightweight. However, its choice is only interesting if it is free from chemicals.

BPA and risk of estrogenic activity

Keeping hot drinks in a plastic container has been found to release BPA and other chemicals. Bpa is a chemical that destabilizes estrogenic activity in mammals.
Other types of chemical agents

In addition to BPA, however, plastic can also contain other chemical agents harmful to our health. Thus, it is best to use it only for storing cold foods and drinks.

What material to consider in this case?

To avoid the various risks of contamination, you can always opt for metal or glass containers.


Metal insulated bottles are ideal for keeping both the heat and the freshness of your drinks. Stainless steels should be prioritized in this category.


Glass containers are suitable for food and drink of all temperatures. Also, a transparent bottle makes it easy to check the beverage level.

How to choose an insulated water bottle?

Here are the criteria you must consider before purchasing your insulating bottle:

Size and capacity

The size and capacity of your insulated water bottle should match your drinking needs. Know that these gourds often exist in 500ml variants, 750 ml, 1 liter, and 1.5 liters.


Whatever material you choose, make sure it is food grade.


Insulated gourds come in a variety of shapes. The flat models save space but can have a relatively low capacity. The bottle-shaped ones are classier, and the cylindrical models are more sporty!


Regarding the cover, if your hands are often busy, prioritize a quick opening system. If you use the utensil at home or in the office, a screw-thread opening with built-in cup capability is a good thing.

Temperature holding ability

The excellent quality of your gourd is attested by its ability to maintain temperature. If you plan to enjoy your drink throughout the day, a 24-hour hold is a priority. If the glass is finished in the hours following bottling, 12 hours of maintenance are sufficient.
