The Vapur 0.7 L Wide Mouth Water Bottle is no water bottle, it's an Anti-Bottle. What does it mean to be an Anti-Bottle? It means reusable, foldable, attachable, freezable, sustainable convenience, all in one easy to grip, streamline bottle. Its a flexible product made specifically with active lifestyles in mind. The Anti-Bottle defies all the laws of what a water bottle "should be". It's also BPA free, and super easy to wash. The Vapur 0.7 L Wide Mouth Water Bottle lays flat when empty and has the ability to be folded and stored where other bottles cannot.
