Cuben fiber is an ultra lightweight, rip-stop, composite laminate used in ultralight backpacking tents, tarps, backpacks, stuff sacks and clothing. It is 100% waterproof, has it has a high strength-to-weight ratio and is easily repaired with tape. While extremely strong, one of the major drawbacks to cuben fiber is that it is not as abrasive resistant as nylon.
The name Cuben Fiber was coined by the press in reference to America³ (pronounced America Cubed), the winner of the 1992 America’s Cup. During the 1992 Cup, that yacht reportedly used sails made from precursors to the currently available commercial product. In late 2007, the Cuben Fiber Corporation was acquired by North Sails. North Sails said they would continue to supply the materials to competitors on an as available basis. Cubic Tech Corporation has the exclusive rights to develop and sell “Cuben Fiber” type laminates for all non-sailing applications.
