Combining 26 years of kite testing with Christoph Fokken is what it took to build our Levitation Delta Kite. Made of lightweight 40-denier ripstop nylon with a fiberglass frame, it has an oversized keel and trailing edge flap for stability. In light winds, bigger is definitely better. Our 9-ft. delta kite hits a sweet spot. A gentle floater in light winds, it has a manageable pull when the wind comes up.
