I just finished my first G4s. The yellow one is mine, and the red one is my wife's. They turned out pretty good. My wife is 5'4", and I was going to followed the instruction on building the pack for smaller framed people. After measuring my wife, I determined that those alterations would not be enough. I had to take three inched off the waist belt, and an additional two inches off the shoulder straps. It fits her like a glove.
