Name: Vapur-16 Anti-Bottle
What it is: Vapur Inc. is a California company that makes the Vapur-16 Anti-Bottle, a collapsible BPA-free "fold and go" plastic water bottle. It comes with a sport-bottle spout and a carabiner clip and is available in five colors: blue, pink, green, smoke and purple, though green is currently out of stock. It's designed for maximum flexibility and can stand when full or roll up or lie flat when empty. Vapur's Web site points out that the financial expense and environmental impact of drinking bottled water is immense and most U.S. tap water is among the best in the world.
The good: The Vapur makes it easy to be a more eco-friendly traveler wherever the tap water is good to drink. It takes the hassle out of wanting water on the plane or in the airport. I carry my empty Vapur either rolled up in a pocket or attached by its carabiner clip to my suitcase. Once I clear the security checkpoint, I fill it up at the nearest water fountain. For road trips, you can fill it, then freeze it, so you have cold water to drink while traveling.
The bad: The top of the sports cap is easy to lose, and I lost mine within a couple of months. I wish it could accommodate hot beverages, but then it wouldn't be a collapsible plastic container.
Cost: $8.95 or a Family 4-pack for $29.95.
