This flexible silicone cup comes in handy when you don't want to buy an expensive water bottle at the airport but still need to keep hydrated. Simply fill it up at the nearest drinking fountain for free after passing through the airport security lines.
It's also great for camping when you don't have a lot of extra space and want to condense as much as possible. While you're at the campsite, you can use it as a regular cup, but afterwards you can fold it flat into your duffel bag.
Finally, it's free of chemicals like BPA and phthalates so you can drink from it without worrying that you're ingesting those kind of toxins.
