A little more info would be helpful. Like her height, and what she plans to do with the pack? Hunting? Backpacking? Approx expected load? There is nothing gender specific about the Kifaru packs that I have found, since they are all adjustable to a persons specific size
I have the KU5200, and have a few miles with the bikini frame and duplex frames (with various bags) as well. at 5'3 and around 135lbs and using a small waist belt I can carry them all I decide which one I want to use based upon what type of trip it will be distance wise and how much I expect to have to haul.
