It Keeps Water Cold
People are maniacs for cold water, which is one of the big things a Stainless Steel Water Bottle can offer. Unlike plastic bottle that poses threats to the environment, the stainless steel water bottle is a double-walled and insulated bottle and is also eco-friendly.
How It Works
A double-walled thermos works by eliminating solid conduction between the inner wall and the outer wall.
A vacuum between those walls stops gas convection from occurring, and so it helps keep cold drinks cold and hot drinks hot.
A copper lining that improves hot/cold retention around 10~15% performance.
Make It Last
Dish-washing is the scourge of double-walled insulation. The heat can damage the vacuum, so it’s better to wash these water bottles by hand. This is where simplicity reigns supreme, since bottles with fewer moving parts become easier to scrub.
