Ready, sip, go.

These collapsible wonders are making all of our sustainable dreams come true. Every cup is made from recyclable materials that are safe for enjoying both hot and cold drinks on-the-go, and—bonus—they’re microwave friendly. (Did we mention you get a 12 oz. and a 16 oz. cup in this set?) Plus, the larger one comes with a reusable straw that folds up inside for simple storage. When you’re done sipping, go ahead and pack it down into a leak-proof disk for easy transport—or toss it in the dishwasher so it’s ready for tomorrow’s smoothie!
