I use a 1-lb Granite Gear pack and put the shoulder straps over my Kelty frame - sort of like the packframe is a person. The hipbelt clips on the back side of the frame and I clip the compressor straps around the side bars ofthe Kelty. This keeps the bag snug on the frame. There is room to tie drybags above and below. The bonus, is that I have a day pack with no extra weight. The heavy part is my Kelty frame. The only problem I have had is that the Granite Gear pack is a bit fragile and it now has more patches than origianal material!
