Challenge MCZ Laminates are ultra-high performance racing styles, which use Black Aramid Fibers in the Warp and Cross Ply. The complete product line is complete in two colours: White and Optic Grey. The same three styles are available for those sailors who want to match a high end woven, or a black/grey membrane. Sailmakers can use Challenge to design sails for both markets. These styles are precision laminated in America with light weight taffetas and superior films for high performance.
