Double Wall Vacuum Insulated Water Bottle 500 ml, BPA Free

Water left in a car in Cairo in August comes back at the temperature of tea: hot, and undrinkable by the time you need it.

What Are the Key Features of This 500 ml Vacuum Insulated Water Bottle?

• A vacuum between the walls: the gap between the two layers has had the air pulled out of it, so there is almost nothing for heat to cross, in either direction.
• It does not sweat in your bag: the outer wall stays at room temperature, which is why a vacuum bottle sits next to a laptop or a book without leaving a wet ring.
• 500 ml is a carrying size: about two glasses, and it goes in a bag where a litre bottle does not.
• BPA free: this covers the plastic parts, so it is a bottle you can refill daily.
• Three colours: beige, blue and red, so a child can pick theirs out of a row of school bottles.

Where Can You Use This 500 ml Vacuum Bottle?

• On an office desk through the day
• In a gym bag
• In a child's school bag
• In the car on a summer drive
• On a work site where the nearest cold water is a long walk away

Why Does 500 ml Get Carried More Than a 1 Liter Bottle?

• Cold at the last lesson: the store states six hours for insulated bottles, which is the span a school bag needs.
• For a site with no cooler: where the nearest cold water is a long walk, what you carried from home is the only cold there is.

Material & Build

• Double wall with a vacuum between the layers: the air is pulled out of the gap, which is what removes almost all of the conduction.
• 6 hours hot, 6 hours cold: the figure the store states for insulated bottles.

Dimensions

• 500 ml.
• On a bottle, the diameter is what decides whether it drops into a car cup holder, so measure yours and judge the body from the photographs.

Care

• A vacuum flask is generally hand washed.
