patrik aio foil carbon mastIntroducing the Patrik AIO Foil Carbon Mast. The PVC Carbon 85 mast is the lightest and stiffest alternative to our A. I. O. aluminum masts. At 1940g, it is about 500g lighter than the Alu85. This is a significant difference for freestyle use, jumping, and reduced swing weight when pumping the Foils. The Carbon 82 mast is recommended for freestyle, where a shorter mast gives you more control over the board during rotations, or for use in flat water,
