Lightweight and quality within everyone’s reach . A new light wood core reinforced with a fiberglass box wrapping around the skis provides light and high performance skis with durability and resistance. Wood is the most used raw material in ski production. For years designers have sought after a wood that is lightweight yet durable and strong, yet this goes against nature. A lightweight wood core needs to be supported by production processes and to be mixed with other types of wood to improve its strength; above all it must be wrapped by composite materials which give it torsional rigidity and durability.
