(25) It will be appreciated by those skilled in the art that the pocket area (50) allows a user to insert an additional multi-layer construction and furthermore it may be insert from the inner side of the infant bodysuit, alternatively the outer side of the infant bodysuit.

(26) In one embodiment of the invention, the monolithic membrane consists of co-polyesters and thermoplastic elastomers. Typically the thickness of the membrane may vary between 7-20 microns. However, in a preferred embodiment of the invention, the thickens of the monolithic member is approximately 10 microns.

(27) The inner most collecting layers in general consist of polyester, alternatively polycotton or any combination of the aforementioned. This layers serves to collect moisture and hold it in contact with the monolithic membrane so that transfer of the moisture through the membrane can take place according to the mechanism described hereinbefore.

(28) The hydrophobic innermost liner (40) preferably consist of polyester and is typically an eyelet type of fabric. The purpose served by this layer is to “wick” moisture away from the skin and leave it rather dry, a most desirable property to ensure undisturbed sleep of an infant when wet. The innermost liner (40) being inherently hydrophobic thus operatively serves as transfer layer between the infant's skin whilst remaining substantially dry.

(29) It will be appreciated that each relevant layer may be laminated or alternatively may be loose.

(30) The laminated structure finally includes an outer aesthetically appealing layer (38) which layer may include depictions or wording thereon.

(31) It will be appreciated by those skilled in the art that the elastic bands (20) and (22) respectively serves to define the containment area (17). However, the entire bodysuit may be lined or alternatively manufacture from the multi-layer construction fabric as hereinbefore described.
