Track suit - VKB style..
Some pics of my track suit, used in Superterminal. Built the pants from scratch, cords attached inside it on loops attached in the reinforcing (webbing)
The jacket is a heavily modified rainjacket, and the elastics are attached to the jacket like with the pants. I`ve got handles to hold the jacket tight with, and the tubs are used to widen it all the way. When I let go of the handle, the elastics make the handles and sleew retract making the pull clean and easy.
Putting the cord/elastics on the back makes the armwing smoother, and it attacks the air in a better angle then if in front. (lower angle of attack, means less drag, more speed and thus more lift..)
Enough info for now, you got figure something out for your self you lazy americans..

Peace out,
Andreas
