It's 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. It's a flexible product made specifically with active lifestyles in mind. The Anti-Bottle defies all the laws of what a water bottle "should be". Unlike traditional rigid bottles, it lays flat when empty, and has the ability to be folded and stored where other bottles cannot. It's also BPA free, and super easy to wash. Our Eclipse series bottles have a unique matte finish that will patina beautifully over time. There is no water bottle like it. Let's just say we're rule breakers, but in the best kind of way.
