Stojo Collapsible Travel Cup - 16 oz. ($25)

"I love my Stojo, and it comes with me everywhere," Paiji Yoo says of the popular collapsible design that's made of silicone and is perfect for hot or cold drinks. "It's so easy to use, and is great for taking my coffee on the go because once I'm done, it collapses and easily fits in my bag." You can shop these cups in a range of colors and either a 12-oz. size (the only one that does not include a straw), a 16-oz., or a 24-oz. They also happen to be dishwasher- and microwave-safe, and when you squeeze them down into their most compact form, they measure just two inches in width.
