With its uniquely vented design, the UltraFoil 30 has a very wide wind range. In light winds, its tall airfoils get more lift. The lower vents aid in initial inflation and the upper vents relieve pressure. In strong winds, the dynamic trailing edge vent opens to release a stabilizing jet of air. The 30's high aspect ratio gives this UltraFoil even more power and efficiency. A high angle flier with good, consistent pull, it's perfect for Kite Aerial Photography and Line Laundry. Made of ripstop nylon, it needs no assembly and has nothing to break.
