  • Patent number: 7699827
    Abstract: A pant shaped garment having a rear portion, a front portion, and a crotch portion, a waist opening with a waist edge and two leg openings bordered by a leg edge having a front part located generally on the front portion and a rear part located generally on the rear portion and on the crotch portion. Front and rear portions are mutually connected in two side joins which run from the waist opening to each leg opening. An elongated elastic element is pre-stretched along the rear part of the leg edge of each leg opening. The front portion comprises an elastically extensible material and the elongated elastic element constricts the rear part of the leg edge, thereby stretching the elastic material along the front part of the leg edge. The side joins exhibit a curvature in a direction towards the rear portion that increases in a direction from the waist opening towards the leg opening.
