The Slingshot Formula V4 board has a full-length, double concave shaped hull that breaks the water’s surface and disperses water out and away. That means more smooth water gliding and buttery soft landings. Designed specifically for twin tip riders looking to fly, the Featherlight Tips cut through chop with ease while the Textreme -30/+30 high modulus carbon construction ensures stiff and solid pop off the water. The Formula V4 is for those who demand the best from their kiteboarding twin tip. Coming in at 5.2 lbs (2.36 kg) for the 136cm board, the Formula is the lightest weight, highest performing twin tip that Slingshot have ever produced. With a full-length double concave hull, the Formula provides the smoothest ride and equally soft landings. The Formula has the most explosive pop in our range thanks to the full length extreme High Modulus Carbon Stringer.
