The top layer shrinks a bit more than the bottom layer, but it's not a huge deal. We use these with the duo wraps and they haven't leaked yet.
So much absorbency, and so quick to lay in a duo and go. Only complaint is that once you're on the last rises of a duo, there isn't enough length to cover front to back. It never bothered my kids, but I didn't like how it looked, haha.
