Ground launching harnesses! ... Stripped of all hardware and flaps, all that remains is the harness. The 3-ring system is usable with a grommet and quick link. Risers are NOT included, but I have some older (but functional) full size, wide risers I can throw in for cheap. $75 each...
Ships in a Priority Mail Flat Rate box for $10.
