This is a genuine Terra Incognita replacement cup set for the Duett 1000 and 1200 vacuum flask series, made from 18/8 food-grade stainless steel and weighing just 80 g so you can restore your flask's dual-vessel system to full function. When a cup is lost, dented, or worn, these OEM-matched vessels bring back the Duett's signature two-cup sharing capability without replacing the entire thermos. Available in original Grey, Green, and Beige, they match your existing flask so the repaired set looks and works like new.
Terra Incognita is a European outdoor brand with more than 18 years of expedition experience and its own gear production, and it supplies these cups as genuine components rather than generic substitutes. That means correct fit, correct color, and the same food-grade steel as the originals, extending the life of a flask you already trust instead of sending it to landfill.
Who is the Duett Cup Set for?
This set is for existing owners of the Terra Incognita Duett 1000 or 1200 flask who have lost or damaged a cup. Rather than buying a whole new thermos, you replace only the cups and recover the flask's full sharing function. It is the practical, low-cost fix for a well-used flask, and the eco-minded choice for anyone who prefers to repair proven gear.
Does the Duett Cup Set match your flask and color?
Fit is the whole point here: these are OEM cups built specifically for the Duett 1000 and 1200 series, so they seat correctly and preserve the dual-vessel design. Color matching matters too, with original Grey, Green, and Beige options so the replacements blend with your existing flask. Confirm your Duett model and color before ordering for a seamless match.
What is the Duett Cup Set made of?
The cups are made from premium 18/8 food-grade stainless steel, the same hygienic, corrosion-resistant alloy used across the Terra Incognita kitchen range. The steel resists rust, will not hold flavors, and stands up to repeated washing. At just 80 g for the set, the replacement adds no meaningful weight, keeping the flask as trail-friendly as the day you bought it.
