The Apache is in a class of its own. The Apache is without question the largest and highest performance wingsuit available in terms of glide and speed. But most importantly, the Apache is still a fun and easy to fly wingsuit for experienced wingsuit BASE jumpers.
During their work on the Fusion wingsuit project, Tony and Jeff observed that placing the parachute harness inside the suit improved performance by reducing drag. They immediately made a prototype that could accommodate a normal BASE harness, attached via specially positioned zips in the back panel of the suit. This allows the suit to benefit from the improved aerodynamics of an internal harness system whilst still being able to utilize your normal rig. The Apache system basically combines your normal BASE rig with the wingsuit to create an integrated wingsuit / container system.
