Just as Powell's Books revolutionized the bookstore, the Vapur "Anti-Bottle" will make you rethink the way you drink. It stands upright when full and rolls, folds, or flattens when empty. With a reinforcing grommet and custom clip, it's the perfect reusable drinking vessel for anyone hurting for space (you no longer have to decide between staying hydrated and carrying around the latest George R. R. Martin book). And it gets better: the Vapur water bottle is dishwasher safe, BPA-free, and made in the USA. How can you pass it up?
