An absorbing undergarment includes a waterproof pocket configured to attach to a front side of an undergarment. The waterproof pocket includes a sealable opening to receive an absorbent insert and an orifice adjacent an undergarment opening for urine to pass there through. A front panel of the undergarment is designed to attach to the waterproof pocket so the pocket orifice aligns to a front opening of the undergarment. An absorbent insert is designed in shape to be complementary to a shape of the waterproof pocket to maximize surface area. The absorbent insert is urine retentive. A self-sealing opening for a male genitalia portion to pass there through is also included. The waterproof pocket flays open like a butterfly's wings attached at a crotch of the undergarment and is fastened around a perimeter thereof. The sealable opening includes an interlocking groove and ridge that form a tight seal when pressed together.
