It seems like most of the population is on the reusable water bottle bandwagon, which is awesome. Yay environment! But, it seems like a lot of bottles have a few flaws... hard to clean (unless you get one of those tiny little toilet brushes), can't easily put ice in them, only available in one size, etc. Well, meet our new BFF, Alex. The Alex Bottle ($26 - $30) is pretty genius. It seals together in the middle, which offers a whole host of features: easy to clean, interchangeable (make your bottle big or small), usable as a cup, and when empty, the bottom piece can be inverted and fit into the top, so it takes up less space in your bag. Our thirst for thoughtful design (and water) is quenched!
