The Viper - S same as previous Viper harnesses is utilize a carbon fiber backplate. This 330 mm(1.08 ft) wide, gently curving back support system allows the harness to fit as close as possible to the pilot while still allowing 'non-binding' support. Depending on the pilot's height, the backplate is between 800 mm (2.62ft) - 1050 mm (3.44ft) long.
- The Viper-S has an optional Matrix cloth outer skin for drag reduction. This cloth has been proved in the wind tunnel to be the most 'slippery' available at the moment. With the Viper-S, same as with all Viper series you are able to replace the entire outer matrix cloth covering at anytime with a new one.
Employing a lever system which is more reliable than those used in previous models, the Viper-S pilot is able to easily adjust the pitch (the angle of attack) of the harness in flight with his butt-without taking hands off the basebar.
