Vapur: The Anti-Bottle

I do not have one of these, Vapur water bottles, but I thought the concept was interesting and like that it folds up. Perhaps this is something you could use? Details below. :)

Vapur is quite simply the most portable refillable water bottle on the planet. And by making tap water more portable, we hope to make bottled water obsolete. Unlike rigid water bottles, Vapur is completely collapsible. This means it goes more places and fits in tighter spaces than any other bottle. Whether you are hiking the trails, passing through airport security or visiting the museum with your family, Vapur makes water infinitely portable. The highly-durable bottle is freezable, dishwasher safe and BPA-free, which means it can be safely reused again and again.
