Thinking about a (long-term) project to make a pack as custom-fitted as possible, i.e., eliminate *unnecessary* adjustability by shaping the pack to fit just one person.
Looking through older article and posts here, as well as other sources, I'm trying to come up with parameters that vary from person to person, but could be measured and given a fixed length/shape for a custom fit.
Obviously, some adjustability in the harness will still be necessary to accommodate different loads, or to allow variations throughout the day to lessen fatigue, etc.
So far, the critical measurements/parameters I'm thinking about are:
Torso length
Shoulder angle and width (affects angle of attachment of straps to pack bag in both plan and elevation, as well as space between straps and strap width).
Chest circumference
Waist and hip circumference
Hip angle
Contour of back
Any input?
