Abstract
Pull-on garments provided with an intermittent lap seam joining the front region and the back region together at spaced apart locations to provide a breathable seam. In a preferred embodiment, the pull-on garment includes a chassis layer comprising a continuous sheet that defines a from region, a back region, and a crotch region; a first belt layer joined to the chassis layer in the front region; a second belt layer joined to the chassis layer in the back region; elastic panel members positioned between the belt layers and the chassis layers which laminate is mechanically stretched to form elastically extensible stretch laminates in both the front region and the back region in the side panels; and intermittent lap seams joining the front region to the back region at spaced apart locations so as to form the leg openings and waist openings.
