Thermoflask vs. Hydro Flask — Which Is Better?
When it comes to picking the right tools for a rugged outdoor adventure, an overnight hiking trail, or even a weekend road trip, owning a reusable water bottle is undoubtedly the most important part.
Customized water bottles and flasks for the modern man should be a high priority purchase, both for providing personal utility and promoting environmental awareness. Up to 23% of plastic water bottle packaging ends up in the landfill every year, adding strain to the landfill crisis. Intentional or not, owning a reusable bottle helps to reduce this issue tenfold.
Environmentally conscious water bottle options such as reusable flasks support the businesses that care the most about our planet, while also providing the convenience of a temperature controlled beverage wherever you go.
The Thermoflask and Hydro Flask are two such companies, each offering specialized and fully customizable bottles for both hot and cold liquids. Ideal for hikers, travelers, outdoorsmen, and more, vacuum sealed flasks are an intelligent investment for any kind of adventure.
What Are Vacuum Insulated Water Bottles?
Contrary to popular belief, hot water bottles and vacuum insulation bottles are actually two separate things.
Vacuum insulation technology supports beverage temperature regulation by preventing liquids from transferring heat or cold in three ways: By radiation, through convection, or via conduction.
- First, a silver or stainless steel coating on the interior portion of the flask removes the possibility of temperatures radiating out of the bottle and escaping the liquid.
- Secondly, the empty space or vacuum between the double walls of the flask reduce the possibility of heat moving by convection.
- Finally, the thin layers that make up the interior chamber of the bottle keep both hot and cold liquids from escaping through conduction, reinforced by the exterior casing that add even more insulation to the bottle.
This dynamic water bottle design is not a new technology. In fact, Scottish scientist Sir James Dewar created its first prototype in 1892. Now over a century later and available worldwide, companies such as Thermoflask and Hydro Flask have perfected the vacuum insulated bottle, adding a host of new developments and benefits.
