My venture last weekend reminded me that my old Osprey pack and my year-old Kifaru Duplex frame pack both rub the top front of my hips raw. Naturally, the center of the belt wants to rest on the top front of my hip bones (tall skinny body type). However, after it starts rubbing, I move it lower so the belt seems to "hug" my hips as opposed to sitting on top of them. After a short time walking with the belt "hugging" my hips, it always moves back up so the pressure is on the top front of my hips. My guess is the weight of the pack slides it lower on my back, causing the belt to hinge upward. Has anyone else come across this and know of a solution?
