Abstract
A diaper construction is disclosed including a pair of elastic leg seal members extending longitudinally of the diaper adjacent each side edge thereof, the leg seal members being operable between expanded and contracted conditions, respectively, and moisture-responsive devices initially maintaining the leg seal members in their expanded conditions, whereby when the diaper is worn by a user and the leg seal members become moisturized, the moisture-responsive devices are operable to release the leg seal members, whereby the leg seal members contract into sealing engagement with the user's leg.
