Constructed from premium 18/8 food-grade stainless steel, these cups are engineered for maximum hygiene and thermal resilience. The rugged steel exterior protects against impacts and drops in rocky terrain, while the non-reactive interior ensures your beverages maintain their pure flavor without any metallic aftertaste. Unlike generic alternatives, these cups are precision-molded to thread seamlessly onto both the Fest 750 and Fest 1000 models, maintaining the sleek, aerodynamic profile of your flask during transport.
Weighing in at a mere 1.76 oz (50g), these ultralight vessels add zero unnecessary bulk to your pack. The stackable design and rust-resistant finish make them an essential spare for long-haul expeditions, overlanding rigs, and backcountry survival. Trust in genuine Terra Incognita components to provide the reliability and durability required for a lifetime of rugged outdoor service.
PRO-TIP FOR EXPEDITION USE: To keep your beverages hotter for longer, pre-heat the replacement cup with a small amount of boiling water before pouring your drink. This prevents the stainless steel from absorbing the heat of your beverage, ensuring your first sip is as warm as the last.
