The Frontier Collapsible Cup (400 ml) combines minimalist design with smart performance. Made of fibreglass-reinforced nylon 66 (bottom, rim, gripring) and food-safe, BPA-free silicone, it folds down to less than 2 cm thick - ideal for backpack or jacket pocket. At only about 53g, it is light enough for ultra-light backpacking trips, but the sturdy rim makes it heat-resistant and comfortable to hold.
Nestles seamlessly with other Frontier dinnerware as well as the 2 L Pouring Pot, for rattle and space savings. The multifunctional combination of nylon and silicone was awarded a Gold Design Award 2023 - a nod to smart design.
