Hi.
I'm 5'4 and I couldn't adjust the Swing so that it fit in the small of my back area, where it was most comfortable, but didn't come too far off the top of my shoulders. When it hit at my shoulders, then the bottom hit near my tail bone which was ackward. It can be adjusted to two different positions but neither one solved my problem. When I talked to the store owner, she was really surprised I couldn't get it to fit comfortably. Maybe it's just my body shape or something. I was actually sad to return it. It seems like a great backpack, very light and sturdy. Maybe it will work for you.
