On the French market, it can be difficult to find the one that will fit your lifestyle if you don't have an excellent guide.
Indeed, the best isothermal bottle is first of all the one that is made of stainless steel for a better temperature retention. Then it should be the right size and shape for your needs as well as a solid seal. Finally, it must be easy to maintain and affordable.
And to help you better understand all this, we offer you this complete guide that takes you to the discovery of the 5 best isothermal bottles. But first, let's take a look at the target and the criteria that characterize a best insulated bottle.
Who can use an insulated bottle?
Basically, anyone can use an insulated bottle, especially the health conscious. However, it is possible to determine a category of people with whom the thermos is more effective.
First of all, there are athletes and nomadic people. If you are a sports lover, it is important to have your insulated bottle next to you. After an intense workout or a walk, it is the best way to hydrate yourself to make up for water loss.
On the other side, workers can also use the stainless steel water bottle to carry hot coffee or juice to the office. Finally, the jar is useful for children who love to leave for school with hot chocolate or any other liquid food.
How to choose the best isothermal bottle?
While there are dozens of options on the market, there are a number of factors that the best insulated bottles adhere to. So, simply base your choice on these to make a custom one.
Choose based on the design material
Selecting the right material is essential to finding the right insulated bottle. For this purpose, stainless steel is the option you should go for. Let's take a look at the reasons behind this spontaneous choice.
Stainless steel bottles are usually designed with a double layer of insulation that can withstand the temperature of any season. In fact, they are able to maintain the temperature of whatever you drink, whether it's hot or cold. Better still, this insulation of the bottles designed in stainless steel retains the internal temperature for hours.
On the other hand, this type of water bottle prevents condensation and does not transmit heat or cold to your hands. Finally, the risk of flavor transfer or change is eliminated, which means your drinks will always taste good.
Stainless steel is a material known for its durability over time. Bottles that incorporate it in their structure are therefore the ideal partners to accompany us throughout our active lives. Indeed, they resist very well to shocks, spills and extreme temperature changes.
Respect for the environment
If you are an ecology lover, stainless steel bottles will make you happy. Obviously, they are free of chemicals such as BPA and bps. So you can use them to stay hydrated all day long without any potential damage to the environment. They are also reusable and easy to wash.
In addition to stainless steel, there are other materials that also offer you a better preservation of your drinks. It should be noted that they cannot compete with stainless steel. However, we suggest you discover them in order to better reinforce your ideas of choice:
- Glass: a glass insulated bottle is durable and stylish, making it an ideal option for long-term use at home and in the office. It is also an excellent investment as it is safe to use. However, it is not unbreakable and can be heavy.
- Aluminum: Aluminum bottles are the optimal choice for cyclists, runners and travelers. They are lightweight and most have a strap for easy attachment to a belt or backpack. Finally, aluminum is ecologically sustainable, but we remind you that it is easily dented and heats up very quickly.
- Plastic: With its affordability, ease of cleaning and variety of designs, plastic is the most popular material. Nowadays, it is possible to find plastic water bottles that are environmentally friendly.
Finally, we remind you that the majority of plastic, aluminum and glass models are not intended for insulation, unlike stainless steel.
Choose according to the shape and size
Having a water bottle that fits in your hand is essential, as it will be easy to hold for long periods of time. There are shapes to hold a cold drink and others to hold a hot drink. In any case, the best choices are round and square shapes. While the shape can be adapted to suit your personal preferences, the size is not.
You might think that bigger is better, right? Well, it depends on how many liters you drink daily. On the market, there are medium sizes of 450 ml or 500 ml and large sizes of over 1 liter.
Choose according to the waterproofness
Your insulated water bottle can fall. However, it would be a shame to notice that its contents have spilled and perhaps ruined the table or objects around it. Therefore, a model designed to be waterproof is always a welcome feature.
For this, you need to make sure that the mechanism of the bottle cap can prevent any kind of leakage. And if you don't know about insulated water bottle lids, here are some examples for you:
- Straw caps: they are perfect for children due to their ease of use, but not recommended for intense exercise like cycling.
- TWIST and screw caps: they fit bottles with a large opening and allow you to drink large amounts of water at a time. They are also easy to clean.
- Push 'n' pull caps: This is one of the most popular options among sports bottles. They are very easy to open for hydration during a workout or while cycling.
- Screw caps with nozzle: they allow you to consume your drink in small quantities and are suitable for hot liquids so as not to burn your tongue.
On the other hand, we can't end this section without warning you against plastic lids with bpa. Most are of poor quality and will gradually seep into your water.
Choose based on shelf life
Generally speaking, the temperature retention time of your insulated water bottle depends on the liquid you put inside. The brand the bottle is made from also comes into play, but the numbers aren't always the same.
In fact, some manufacturers claim that their bottles will keep liquids cool for 24 hours. On the other hand, others state that theirs will keep freshness for 48 hours. All of this may be behind advertising issues and it is impossible to contradict these claims without testing.
However, at Healthy Lunch, you can be assured that our insulated bottles will retain their freshness for at least 24 hours. When it comes to hot drinks, our tests ensure a minimum of 12 hours of shelf life.
Choose according to the level of cleaning
The best insulated bottle is the one that can be easily cleaned to avoid the accumulation of mold and scale inside. To this end, it should be cleaned with liquid soap and white vinegar.
How to clean your insulated bottle with liquid soap?
For most uses, hot soapy water will suffice. Simply fill the bottle with hot water and add a few drops of liquid dishwashing detergent. Then, place the cap on the bottle and give it a good shake.
Then, empty it and use a scrub brush to reach the bottom of the bottle. Also take the opportunity to wash the outside of the bottle.
Once you're done scrubbing, rinse your jar with warm water until you see no more soap bubbles and let it dry completely. Scrub the lid inside and out as well. Finally, rinse and dry!
How to clean your insulated bottle with white vinegar?
Basically, vinegar is a traditional cleaning agent. To use it in the cleaning process, fill your flask halfway with water and pour a little white vinegar inside. Put the lid on and shake the container, then let it sit overnight.
The next day, be sure to rinse the bottle and cap with warm water to remove any remaining vinegar. Finally, turn the bottle upside down and let the remaining water drain out.
These procedures may seem time consuming, but they will keep your insulated bottle looking great for a long time.
Choose by price
Price plays a huge role when you buy anything and the insulated bottle is no exception. We understand that you want to get your money's worth. Fortunately, the best insulated water bottles are relatively affordable and shouldn't break the bank. In our catalog, there is a wide variety of models that fit any budget. Just take a look and choose the bottle that fits your budget.
How to take care of your insulated water bottle?
Once you have selected your best insulated bottle, it is necessary to take good care of it to constantly enjoy it. Technically, it is about avoiding unnecessary exposure of the jar to shocks.
To do this, consider keeping it in a secure foam pouch or compartment in your backpack. Next, make sure your bottle is snug and securely installed in said pouch.
On another note, you'll need to keep the bottle hygienic to prevent its vital walls from wearing out over time. Here are our best tips on this subject.
First of all, make sure you empty your bottle regularly. It's crucial not to leave half-filled bottles lying around with stagnant water. Once you get back from your hike or sport, empty the remains of the bottle as soon as you get in. Finally, rinse it out a bit and leave it upside down to drain.
