Claim:
A pair of pants comprising a L pocket, a belt section having a padding material, a primary elastic material connected to the belt section and a structure to enable the belt section to expand and contract around a waist area defined by the belt section so that an apparent length of the belt section is allowed to increase and decrease by the primary elastic material: the belt section comprising; a doubled section essentially consisting of two sections, the doubled section being positioned near an upper part of an outer edge part of the L pocket, while the outer edge part of the L pocket is located at a side of a front center of the pants; a storing section defining one section of the doubled section, the storing section having an inner sheet and an outer sheet so as to form an inside space therein, and the primary elastic material being provided at the inside space of the storing section, the storing section having an opening end of the inner sheet and an opening end of the outer sheet formed into a vertical line, respectively, so as to be substantially perpendicular to a longitudinal direction of the belt section; an elongating section defining the other section of the doubled section, the elongating section having one longitudinal portion inserted in the inside space of the storing section so as to be covered by the storing section, while the elongating section having the other longitudinal portion protruded from the storing section, the elongating section being connected to the storing section via the primary elastic material so that the elongating section is movable to allow the belt section to expand and contract; and a non-stretchable fabric piece provided at the inside space of the elongating section, the fabric piece having an upper end and a lower end, and the upper end of the fabric piece being sewn at an inside of the elongating section from a first longitudinal location to a second longitudinal location of the storing section, the second longitudinal location of the storing section being located close to the front center of the pants, while the lower end of the fabric piece is sewn on a lower end of the belt section.
