The Sea to Summit Frontier Ultralight Collapsible Cup is the latest and greatest in collapsible drinkware after over a decade of experience. It's sleeker, lighter, and more ergonomic than ever before! With a base, rim, and center ring made from glass-reinforced nylon 66, you'll have no trouble getting a good grip on this bad boy. And, of course, the sidewalls are made from EU food-grade silicone rubber, which lets it collapse to less than 2cm in height. Because who wants a regular cup that can't collapse, am I right? So go ahead and stack 'em or nest 'em, these cups are the perfect choice for any situation!
