About Cool Bottles™

Good question.

Thanks to our unique Triple Cool technology™ with triple layer insulation, which includes a copper layer, our products are able to keep any liquid hot or cold for long periods, keeping the outside completely free of condensation.

All of our tumblers contain this Triple Cool™ technology, which keeps drinks cold for 16 hours and hot for up to 8 hours. In addition, we are progressively incorporating it in all our bottles, reaching 36 hours with your cold drinks and 18 hours hot. In each of the articles, you can see in the product sheet, the specific characteristics for the design/color and size chosen.

However, the rest of Cool Bottles™ achieve, thanks to our double wall technology, a vacuum insulation that allows your bottle to keep any type of beverage cold for 24 hours and hot for up to 12 hours. In addition, the double wall prevents external condensation, so Cool Bottles™ will not sweat in your hands, backpack or bag.

For everything, we want it always with you

It adapts to you and your hydration needs throughout the day. Don't forget to share those moments by tagging us with #JointheCoolers on social media!

Watch out! This is important!

All our bottles are made of high quality 18/8 food grade stainless steel. This material is inherently safe and has a very high rust resistance. In addition, it does not require any coating. Cool Bottles™ does not contain Bisphenol A (BPA), making it a healthier and safer choice than single-use plastic bottles.

The million-dollar question.

Landfills and oceans are full of water bottles. Plastic recycling rates barely reach 10% so everything else goes back into our environment. Considering that a plastic bottle takes 450 years to degrade and that the massive use of plastic does not take more than 60 years, it is easy to understand the magnitude of the problem. The current situation is not sustainable.

In fact, the use of plastic in the bottled water we see in supermarkets is only the visible part of the problem, the tip of the iceberg. In order to have these bottles available on the shelves, it is necessary to have a long process involving the production of the plastic bottle, its filling, transport and storage. Each of these steps requires large amounts of energy, thus producing pollution.

Cool Bottles™ is designed to last, and to offset its own production with a few uses. Not only will improve your hydration, but you will free the planet from disposable plastic bottles.

Yeah. They’re designed just for that.

Unlike aluminium bottles, the 18/8 stainless steel we use to make Cool Bottles™ does not require any plastic coating and is ideal for containing and maintaining all kinds of liquid. Aluminium is not suitable for contact with food and beverages, especially if they are acidic or hot, being highly toxic in these circumstances.

Oppositely, Cool Bottles™ can contain any type of drink, regardless of whether it is hot or cold or if it is acidic, sweet or carbonated. It does not add any extra flavor or release harmful substances.

Yeah. Goodbye to worries.

Our high quality 18/8 stainless steel products are completely BPA-free. Unlike aluminium bottles, Cool Bottles™ 18/8 stainless steel does not require any internal plastic coating. In this way, Cool Bottles™ completely avoids the release of extremely harmful substances such as BPA.

In our bottles, the internal part of our caps are made of 100% BPA-free plastic and silicone. In fact, the plastic used is the same BPA-free plastic used to produce feeding bottles for babies.

On the other hand, the lid of our tumblers has Tritan™ as its main material. Tritan™ It is a copolyester resin totally free of BPA which has similar features to steel, such as resistance to breakage, lightness, no transmission of smells and even, the capability of using it inside microwaves and dishwashers. In addition, the lid of our tumblers has a high transparency taking advantage of the properties of this revolutionary material with excellent resistance to thermal shock.

Yes. Our bottles and tumblers are completely airtight.

All our products are completely airtight. Both bottles and tumblers. They require, however, to be closed completely to ensure the hermetic sealing.

Our bottles contain a silicone ring which allows a total sealing thanks to the screw cap. Full safety to accompany you in your backpack or handbag.

Our tumblers have been developed specifically to be completely airtight. Goodbye to all doubts: always with you.

Oops! We don’t recommend it.

In fact, the triple layer of the Triple Cool™ technology will avoid, respectively, cooling or heating the drink to the extent that it would occur in other containers. In addition, the volume of liquids may vary due to the temperature change, affecting the walls and, consequently, its thermal capacity.

Thus, liquids should be poured into your Cool Bottles™ at its consumption temperature... And your Cool Bottles™ bottle will take care of keeping your drink cold for 36 hours or hot for up to 12 hours! (16-8 in tumbler’s case).

Please note that this same criterion applies to any other product manufactured with double wall.

No. That’s not the idea.

Your Cool Bottles™ will help keeping your drink fresh for many hours, but it is not intended for long-term storage of liquids.

In addition, drinks with alcohol, juices and dairy-based beverages, can spoil and may cause excessive pressure buildup in your bottle or tumbler, causing possible injuries when opening the cap/lid.

That’s what it’s for. It’s your travel companion.

It does not represent any problem in the security controls. Just remember to empty it before passing them. Have a nice trip!

No way! You are the one doing sports, but not your Cool Bottles™!

Cool Bottles™ technology generates a vacuum insulation which avoids external condensation. In fact, the outside temperature of the bottle will remain the same regardless of the content in it: bye-bye to your hands suffering the temperature of your favorite drink.

Our products are thoughtfully designed in Spain and responsibly made in China. All our factories are audited and comply with most strict ethical and environmental practices.

Sadly, there is no stainless steel manufacturing industry in Spain. Nor even nearby. In fact, the vast majority of the world’s manufacture of stainless steel products for daily living is concentrated in Asia.

The bottom problem is the stainless steel with which we design our products. It is the best available material, but there is no chance to manufacture it in Spain. The local options are based on aluminium, plastic or even glass, but are in no case as healthy or capable to manage thermal insulation as stainless steel. We firmly believe that stainless steel is the best choice for mass adoption of reusable bottles.

In addition, we think that the sustainability that we provide is not so much in our product itself (which also), but in the impact in what we stop consuming. The end result, the reduction in consumption of single-use plastic bottles, is the brutal impact that we actually get.


Care & Caution

Taking care of your Cool Bottles™ is easy.

We recommend cleaning your Cool Bottles™ regularly, especially if it is used to store a liquid other than water. We recommend hand washing with warm water, mild soap and, in bottles case, with a brush.

Our Cool Bottles™ products are not dishwasher safe as they it can chip the paint and affect its thermal capacity.

As an exception, the lid of our tumbler can be cleaned in the dishwasher. With more nooks and crannies, we have designed it to allow easier cleaning.

Once washed, let your Cool Bottles™ dry upside down and store it without the cap/lid: this will help your Cool Bottles™ keep looking and smelling fresher.

Our products should only be used for their intended purposes described above.

Do not place your Cool Bottles™ in the microwave. Do not place your Cool Bottles™ in the freezer or refrigerator. Do not place the main body of your Cool Bottles™ in the dishwasher. Do not overfill your Cool Bottles™. Hot liquids may burn you. To prevent spills and leaking, cap or lid needs to be fully tightened to ensure the airtight seal. Do not use your Cool Bottles™ for long-term storage of liquids. Alcohol, some juices, and dairy-based beverages can spoil and create extra pressure, causing possible injuries when opening the cap/lid. You can use your Cool Bottles™ with carbonated drinks. However, be careful when opening it as you could stain or damage yourself with internal pressure.

Yeah. It’s designed for that.

When we designed our tumbler, we decided that the lid would be resistant to the high temperatures generated by a dishwasher to be able to completely clean all its nooks and crannies.

In fact, our lid is made of Tritan™, which allows you to have a very high thermal resistance and, therefore, being able to wash in the dishwasher.
