Libero Comfort have our patented ‘Libero Drytech' surface, which transports wee away from the surface of the diaper faster than any other material. A dry diaper reduces the risk of skin irritation. All the diapers between sizes 2 and 7 have Free Flex stretchy sides and Velcro fasteners. With the help of these smart, stretchy elastic strips and fasteners, the shape of the diaper adapts to soft thighs and round baby stomachs. Along with the narrow gusset between the legs, this makes sure that the diaper is comfortable and does not leak. Instead, our diapers breathe. They allow air to circulate, while the outer layer and core remain perfectly dry against the skin, which is best for small babies' bottoms.
