A flexible, breathable laminate is provided for use in, for example, hospital gowns ortents, which is capable of preventing liquids from passing inwardly while at the same time permitting water vapour, such as perspiration, to pass out outwardly. The article comprises an inner layer of hydrophobic material (2) having a moisture vapour transmission rate exceeding 1000 gms/m2 day and an advanced water contact angle exceeding 90 degrees, and an outer attached layer of hydrophilic material (4) having a moisture vapour transmission rate exceeding 1000 gms/m2 day.
The outer layer can contain a solid particulate or a liquid , additive, such as a pigment or antistatic compound, the layer (2) optionally being attached to a textile layer (6).
