The US trashes 58 billion paper cups every year – a fact that disgusted Karla Zens, a San Francisco-based sustainability pro and coffee lover. Opting to go the reusable route, Zens found traditional travel mugs too bulky and existing collapsing cup designs too flimsy and unfit for hot beverages. In response, she created Zip Cup, an easy-to-carry, spillproof travel mug that collapses to the size of a ball of socks! Stylish, dishwasher safe and free from harmful additives like BPA, the cup comes in an array of colors and designs sure to suit all tastes.
