From 10,5 kg, we follow a unique manufacturing process during which all layers of fabrics, reinforcements, and casings are applied in a double-shell mold, then baked following a process allowing an ideal polymerization of resins for a perfect reproduction and an optimal weight/solidity ratio. The resin used for the construction of our boards is a biosourced epoxy SR GreenPoxy (more than 33% of the molecules come from plant sources). What is included? The Zen 170, 190 and 220 boards include a daggerboard and fin. The Zen 150 does NOT have a daggerboard, but includes the fin.
