Rookie Monofilm Complete Rig EPX 3.5A lighter learning rig for young riders. Small riders face a different challenge than adult beginners. The rig has to be light enough to lift, manageable enough to control, and stable enough to build confidence all at once. Too heavy, and the learning stops before it starts. The Rookie is built specifically for young windsurfers. A lightweight monofilm sail designed to give kids the stability and simplicity they need to enjoy every stage of learning.
