The Matbock M3 SkyFins (M3 for Matt 'Maddog' Mason) are intended to give a military freefaller the same sort of increased control and maneuverability that civilians get from skydiving pants. The increased surface area improves control and allows you to track further. They're made of 500 Cordura and synthetic leather, feature an integrated VS-17 signal panel on each leg (the two can be combined) and are currently available in MultiCam and Coyote.
