Thanks, I think I worded my original post wrong.
She won't be carrying much more than 10lbs. Thats the reason I need a backpack that will carry closer to 30lbs, so her load can be lighter.
I already have an internal framed one, but its heavier than I prefer. So if someone has something closer to 2lbs (GG gorilla, etc?), that is what I am looking for.
