Paying for bottled water is not only financially wasteful, it’s a bit of a dick move for the environment. The Hydaway is a collapsible, reusable silicone bottle with a plastic framing that expands into a 21oz. or 12oz. container in a couple of seconds. When collapsed it’s only 1 1/4 inch thick, and has a convenient carry handle that can be clipped to a bag. It’s watertight, BPA-free, and fully dishwasher safe. If you want your own, it’ll only cost you a $20 pledge on their fully-funded Kickstarter, and you can expect to get it in August of this year.
