It says it fits torso lengths of 14-21 inches...how do you go about measuring torso length? My wife is all of 4'10"...I'm guessing she's not going to meet the minimum and we'll have to get the shorter shoulder straps, but hopefully not if we can just figure out how to measure her torso!
Basically you measure from the last neck vertebral spine which is the big bump at the bottom of your neck in back (C7 or vertebra prominans) to the vertebrae that is even with the top of the iliac crest ( the pelvic bone that stands up the highest). If you go to you tube and enter measuring torso length you'll find numerous videos that will walk you through it. Good Luck!
