Double Wall Vacuum Insulation
You might be asking yourself right now, “What’s so special about a Hydro Flask® and why should I drop my hard-earned cash on yet another reusable water bottle?”
So let’s start with a simple science lesson.
Everything that has matter conducts heat, including water, air, plastic, aluminum, and stainless steel.
A vacuum is created when all of the air is removed from a sealed object. In other words, a vacuum is a space that is empty of matter, and each Hydro Flask® contains a vacuum seal between two walls of food-grade 18/8 stainless steel.
(If you’ve already figured out that a vacuum is a terrible heat conductor because it’s composed of almost nothing, you’re way ahead of “the other guys.”)
Our patent-pending double-wall vacuum insulation means that the temperature outside a Hydro Flask® has a very hard time affecting the temperature of whatever you might put in it. The best part is that this is a two-way street; whether you’ve got hot or chilled liquids inside of your Hydro Flask®, the internal temperature won’t affect the temperature of the container in your hand. That means no blistered fingers with your daily cup of Joe, and no troublesome sweat rings—from your bottle of ice water. Hydro Flasks® are pretty amazing, but we can’t make guarantees about individual personal hygiene practices!
At Hydro Flask®, our designers didn’t come up with “yet another reusable water bottle.”
They’ve created a technologically superior piece of hydration gear, one that puts a double-wall vacuum insulated barrier between itself and the competition.
