When I did my 1300ft Skydive for Charity,on my 80th Birthday,---I was very careful to adjust my harness, with great care.
The Instructors (Who knew I was an ex-Pra) had the giggles !
Two straps come up between the legs, and, if not properly adjusted, snap together as the main 'Chute opens.
"Amateurs" speak in a high-pitched voice for a few days !!

This did, not, of course, apply to the ladies present, but there were none in my day !!!
