Actually, it turns out that the hip belts I bought are from a MOLLE - just arrived yesterday. Seems to work great on backpack #1, but I guess I will find out for sure when I actually use it on a trip. Has to be an improvement on the old nylon web strap, which wraps around at about mid-hip level, and doesn't do much more than anchor the bottom of the pack. Backpack #2 resides at my Dad's house, so won't get to install until the next time I go up there.
