The CHS challenger 4G is a signature wave sail shaped and perfected with the insight of Alex Mussolini — the same rider who once called it “perfect.” Even after stepping away from the professional tour, Alex remained personally committed to ensuring his sail continued to evolve for 2024, preserving the feeling and performance that made it iconic.
This 4-batten design delivers a rare combination of lightness, stability, and punchy power. It accelerates when you need drive, loosens instantly when you demand agility, and stays balanced through every turn. Whether you’re carving tight bottom turns or hitting critical sections, the 4G makes even complex manoeuvres feel intuitive and controlled.
Built for modern wave riders who want a sail that responds instantly and never weighs them down, the 4G carries the DNA of a champion. When someone who has won the Aloha Classic helps shape a wave sail, the result is something truly special — a sail created by someone who knows exactly what makes a fantastic wave-riding machine.
