Frontier Collapsible Cup builds on over a decade of experience in collapsible drinkware - engineered to be sleeker, more ergonomic and lighter than ever before. Glass reinforced nylon 66 is used for the base, rim and center ring providing more stability and allowing you to grip the cup more easily. EU food-grade silicone rubber sidewalls let the cup shrink down to less than 2 centimeters in height. Designed to nest and stack, these cups really do fit in anywhere.
