These aren't anti-matter, Auntie Em, or antioxidant... they're anti-bottles.
But what does an 'anti-bottle' mean?
A typical bottle is a rigid container that carries water, while Vapur Anti-Bottles are soft and flexible, can be rolled up for easy storage in your pocket, and barely take up more space than what you fill them with.
They're fantastic for travel - arrive at the airport empty and fill them up after you zip through security.
More convenient and better than paying $6 for a bottle of water at the airport.
Since they're reusable, they're all green... regardless of the color.
