In collaboration with Gerd Dönhuber (German national team pilot),
the SKYLINE HG harnesses Zero Drag FR and Zero Drag SPEED have been reworked and
refinements have been made in a few areas. The new features are being
incorporated now in series production. The back plate was shortened in the front
section. The main benefit of this is to allow greater upwards freedom of
movement for the shoulders, making it easier to straighten up and re-position
and providing better visibility when thermalling. In addition, this change to
the back plate improves the aerodynamic form in the shoulder region.

Additional changes are detailed at the link above.

A good deal of development work, close collaboration with pilots
and development input from top competition pilots means we are constantly making
new findings and incorporating improvements into our products. We are able to
offer an
UPDATE Service , so that all pilots can enjoy the benefit of some of the
latest developments without having to replace their harnesses every year.
Changes can be made to older models of harness, within certain limits, to
improve and update them. The update options vary according to the model and year
of manufacture.
