Since birth my daughter has allergic reactions to many layers, even some brands which claim environmentalists. The discovery of Naty layers is a very good surprise. My daughter no longer has any irritation :-) The layers rise well into the back, they are breathable, soft, comfortable, healthy and at a price quite reasonable. Leaks are few (no more than with other brands). In short, I'm not ready to go back to the leaders of the layer found in supermarkets. Unlike other reviews, I really like my children to agree to surrender their toxic layers on the bottom! Allergies my daughter gave me at least made aware of this. I think Naty layers have good value for money and are a good alternative to cloth diapers (a bit too extreme solution for me).
