After a lot of thought I think I may have hit on a method of balancing SUL pack weight against the relative size of the hiker.
My thought is to start at 5 lbs and add one ounce per inch of shoulder girth above 38 (as in a standard 38 sport coat.)
A guy who wears a size 42 sport coat, for example, should consider 5 lbs, 4 oz as the threshold for SUL.
I consider this as an important caveat in that two hikers, caring the exact same gear, but different sizes, will have a significant difference in pack weight. This can motivate the larger hiker to leave essential safety gear at home that the more averaged sized hiker will leave in.
Waist size is not a good method, because we should all strive to active a more fit and healthy weight for our size, however, shoulder girth is usually somewhat independent of weight.
Similarly, taller than average folk should gain several ounces of handicap for heights over that which a standard sleeping bag will fit.
Just my thoughts to help promote a safer backcountry experience.
