The base panel 1, the front inner panel 2, and the front outer panel 3 are made of elastic fabric, for example, spandex. The overlapped area of the front inner panel 2 and the front outer panel 3 is sufficient to cover the external genital organs of a man.
The main features of the present invention are outlined hereinafter. The base panel 1, the front inner panel 2, the front outer panel 3, and the waistband 4 have the same elastic ratio, The front outer panel 3 has a seam 31 vertically extended and smoothly curved on the middle, thereby forming a convex portion 32 around the middle area of the front outer panel 3. The front inner panel 2 has a first seam 21 smoothly curved and vertically downwardly extended from the midpoint of the top side, a second seam 23 smoothly curved and vertically upwardly extended from the midpoint of the bottom side. The first seam 21 and the second seam 23 are spaced from each other at a distance and aligned in a line, thereby causing a convex portion 22 formed around the middle area of the front inner panel 2. When the front inner panel 2 and the front outer panel 3 attached together and stitched to the base panel 1 and the waistband 4, the convex portion 32 of the front outer panel 3 is suspended in front of the convex portion 22 of the front inner panel 2.
