An undergarment to cover the genitals but not the anus

A garment 1 for men or women includes a waistband 2, a front panel 4 and two straps 6. The front panel extends between the waistband and a junction region (14, fig 2), the straps attach the junction region to the waistband. The junction region is located at the wearer's perineal region and the front panel extends over the wearer's genitalia. The straps extend to either side of the wearer's anus, preferably under a wearer's buttocks and around to a frontal region of the waistband. The waistband and/or the straps may be made from the same piece of material as the front panel. The straps may be adjustable and preferably form an angle of 30 to 90 degrees to each other at the junction. The garment can be worn to prevent, treat or reduce the spread of infection between the anus and vulva, and minimise the risk of perineal abscess formation.
