Understanding The Options

Whether you are hiking through mountainous tracks, running a marathon race or just sitting in front a laptop for your work, whatever the situation is, you will most likely feel the need to quench your thirst. This thirst can be satisfied well by drinking purified water from one of these containers.

You might be confused about where to begin. Although insulated water bottles have become an everyday item, the bottled water industry has exploded recently with bottles of all kinds of shapes, designs and colors by famous brands or new and unfamiliar manufacturers (Source). 

There is an increasing demand these days for insulated water containers which keep their contents hot or cold by limiting heat transfer between its content and the temperature outside of it. This mechanism works with a bit of clever engineering behind it and well-made insulated bottles are able to keep the ice in a frozen state, no matter how hot the external atmosphere is, and it is also capable of keeping the contents of the bottle warm inside even if it gets soaked in icy water.

Each different container design features some specific functions. We scrutinized the various water container designs including the insulate thermoses, citrus-infusing options, flasks with push–button closing mechanisms, and many more. The research shows that the collapsible water bottles are designed to save space and weight, while rigid bottles are built to last for a long time. Metal, plastic and glass bottles are best for storing consumable liquids.


Plastic products have always remained a popular item, most commonly used at local rock climbing crags, campsites or gyms. This is because a plastic water canteens is very light in weight, inexpensive and versatile. Plastic options are mostly transparent, which proves to be good in tracking your water consumption. Moreover, they are strong, durable and don’t rust like metal ones do. And of course, they come in very aesthetically pleasing colors, so you can match your water bottle with your mountain bike or a pink laptop cover, etc.

These canteens are best suited for a variety of actives and can be very handy on backpacking trips or going out for a long campaign journey. But experts have advised that plastics types have the risk of toxins leaking from the plastic into the water and this might be related to infertility or cancer problems later on in life. This is why it is recommended not to use a plastic water product for a long period of time and you should try to use a new plastic bottle every day, instead of using the same bottle over and over.


Stainless steel types have the best longevity and durability qualities. They can last for a very long time if they are handled with proper care. However, with the passage of time, signs of wear and tear, such as scratches and dents will becomes visible on it.

The plastic caps on these stainless products will likely shatter before the bottle will deteriorate. Stainless steel materials are used during its development process and metal water bottles have proven to be free from the health hazards that are common with plastic bottles.


There are many different types of insulated styles available in the market, but some of the best designed insulated bottles are listed below,

  • Double-walled vacuum insulation: As the name refers, the concept behind vacuum insulation is very remarkable. The double wall vacuum flasks achieve their insulation by using two walls with a tiny gap of evacuated air between them. Inside this vacuum flask, there is a gap between the two walls, which prevents any transfer or absorption of heat or cold.
  • Hydro flask: This generation of insulated canteens are also known as flex cap and incorporates the new honey comb insulation technology in its lid. This newly designed cap not only offers improved insulation, but is also a handy carrying strap.
  • Fifty/fifty vacuum insulated: This type of product offers great insulation properties and has proven to the most durable bottle out of all the available options. Well- designed, highly functional insulation comes in a wide range of colors and sizes and are easily available in most shops. These canteens bring all the features required for a water bottle and are considered the best option for insulated stainless steel bottles.

Final Thoughts

The water bottle market is full of various types of insulated canteens, each with a unique design and durability features. But it’s a fact that it is impossible to try all of them. So before buying one yourself, keep in mind that your health is most important, so be sure to pick a non-plastic bottle if you intend to use it over and over again. If you choose plastic bottles, then make sure to discard them after using it for a single day.
