Abstract
Abstract A soft soft-sided luggage case preferably comprises a frame and a pair of hinged side panels which are zippered to fabric portions of the frame around the periphery and which provide unobstructed access to the interior of the case. Abutting portions of the frame and the side panels provide a seal when the side panels are zippered closed. The fabric portion of the frame is frictionally held between two pairs of outwardly facing flanges.
