I’m so glad I made the jump and purchased these instead of synthetic water-proof covers. They really truly do work! We’ve been using these with a single pre-fold or flat cloth diaper through the night and no leakage. They also have a beautiful feel and I love the design. Nicest snap layout I’ve seen on a diaper cover yet. These also have an interesting advantage for EC training! Though the moisture from a pee doesn’t come through, the warmth does very perceptibly, so it’s really easy to tell when baby is peeing (which is helpful for building and affirming the cue.) These are going to be my diaper cover go-to from now on. I also love the colour varieties! I went with greens and I love that each one is different, they are all so nice.
