Abstract: An undergarment having rapid donning and doffing capability without the wearer needing to remove his pants and shoes. The apparatus consists of a single unit of wearable fabric having a body portion and two identically long extending left and right leg segments. Three closure systems, containing male parts and female counterparts, are separated and sewn at opposite, respective sides of the undergarment. The two sides of the body portion are wrapped around the waist in the front of the lower abdomen perpendicular to the waist and the closure system fastened thereupon enveloping the waist, buttocks, hips, and lower abdomen. Thereafter, the sides of the extending left leg segment are pulled around the leg and the closure system fastened along the inner leg thereupon enveloping the left leg. The same process is repeated on the right leg thereupon forming a complete undergarment. Dismantling simply means unfastening all the closure systems and removing the undergarment.
