Abstract: The present sanitary napkin is thin (less than 4 mm in thickness), highly absorbent and has a flexural resistance which provides controlled deformation when in use, namely the assumption of a “W” pattern (good for absorption performance) or a “M” pattern (which enhances comfort).

The sanitary napkin is characterized by a flexural resistance of not less than about 400 g. The sanitary napkin has a cover layer, a barrier layer and an absorbent system having at least one preferential bending zone which allows the napkin to adopt a certain three-dimensional deformation profile in response to lateral compression.
