Armoured over-trousers (10) are formed as “chinks” having an open lateral external flank (13). Protective anti-ballistic armour plate (42), integral with fabric material (22) used for the over-trousers or otherwise incorporated within correspondingly sized, shaped and strategically located pockets (40), protects lower abdominal regions, including the buttocks, upper thigh regions and genitals, of the wearer. The open flank (13) provides mobility whilst ensuring a low thermal burden and access to storage pockets in conventional trousers (14). The over-trousers are secured around the legs by strapping (16, 18) to reduce the possibility of a blast wave (36) funneling effect that might otherwise be experienced should the over-trousers (10) only fit loosely around the legs of a soldier.
