Abstract: A condom is disclosed herein having an elongated sleeve of substantially constant cross-section that terminates at one end in an expandable bulbous portion with a dimpled projection lying along the central longitudinal axis of the sleeve. An elastic retainer band is disposed on the opposite end of the sleeve while a narrower retainer band is integrally disposed between the sleeve and the bulbous portion. A marker is provided adjacent to the sleeve at the bulbous portion indicating the forward end intended to be rolled outwardly to advance the sleeve from its storage position to its elongated operative position.
