Heavy duty Dacron frame is the backbone of our kites. Without sacrificing strength, we were able to take our multiple reinforcements inside the kite, which allowed us to use more dacron on the canopy without adding more weight to the kite. The heavy duty Dacron frame ensures the best strength to weight ratio and makes the kite much more rigid, correctly shaped, stronger and durable. This results in amazing flight stability, more dynamic reactions to rider input and explosive boosts.
