Forged from premium 18/8 food-grade stainless steel, this cup set is built to endure the high-impact environment of alpine expeditions and overlanding treks. The rugged steel construction is paired with a high-quality finish available in grey, green, and beige, allowing you to maintain the aesthetic integrity of your gear. These are precision-molded manufacturer replacements, designed to thread perfectly onto the larger-capacity Duett bodies, ensuring a rattle-free and secure fit during transport.
Each set is optimized for weight-conscious travelers, tipping the scales at just 2.8 oz (80g). The non-reactive stainless steel interior guarantees that your drinks stay pure—no metallic aftertaste, no BPA, and no odor retention. Easy to clean and virtually indestructible, these cups are a mission-critical spare for any long-haul journey. Trust in genuine Terra Incognita parts to keep your expedition running smoothly, one pour at a time.
PRO-TIP FOR EXPEDITION USE: Since the Duett series is designed for sharing, keep this replacement set as a dedicated backup in your vehicle or basecamp kit. The 18/8 stainless steel surface is highly resistant to staining; for a quick field clean, simply rinse with boiling water and wipe with a microfiber cloth to maintain the factory finish.
