FLOATING HARNESS - ADJUSTMENT 

 
Parachutes DOM after January 1988 also have a “FLOATING HARNESS" feature which 
allows for an important fourth adjustment area to custom fit various torso lengths.  With the 
parachute on and over the shoulders, the top of the parachute container is positioned on the 
back at or just below the shoulders (for Seat parachutes, the top of the back vest).  The Main 
Lift Web (MLW) position is now established from the upper torso (chest area) downwards to 
the junction of the MLW and side strap at the upper leg / hip area.  The leg strap should be at 
a 30-45 degree upward angle from the crotch.  For view of a properly fitted harness, see next 
page drawing headed “BACK & CHAIR PARACHUTES.”  Only National’s harness design 
allows for the MLW adjustment which provides an added comfort and safety feature 

without

 

additional hardware and extra weight.   
 
The MLW passes between the two layers of side strap webbing.  On the back of the MLW 
beneath your ripcord handle is a strip of Velcro Loop. On the inside of the side strap is a strip 
of Velcro Hook.  When these two pieces of Velcro are mated your MLW and side strap are 
held in place (so the adjustment position is maintained after removing the harness).  To 
change adjustment, insert your index finger between the two layers of webbing and separate 
Velcro.  Keep finger inserted to prevent Velcro from re-mating while sliding MLW strap to 
desired position.  Remove finger and squeeze Velcro parts together to secure adjustment. 
 
Shown below is close up of the floating harness adjustment area (junction of the Main Lift 
Web and Side Strap).  Velcro inside the junction is used to hold your custom adjustment in 
place for the next wearing.  Or if need be, it can be easily and quickly changed for taller or 
shorter person.
