  • The Challenge Sailcloth Newport brand is the most recent addition to our highest end sailcloth.

    Newport is a complete product line with three main construction types: All Purpose, Low Aspect and Pro Radial. Newport is produced using the best sailcloth fiber available; Challenge Fiber 104.

    This new product line combines all of the R&D Technology which Challenge has learned from the production of famous brands (such as Marblehead, Warp-Drive and High Mass Fiber Weaves). Challenge has designed constructions with very strong fill 1% numbers, rugged denier combinations for AP applications, and strong radial performance in Newport PR. Fiber 104 can pack more fibers in a sail than competing sailcloth. Challenge has developed a mechanical advantage.
