The members, which are typically in the form of a bi-layer glove, comprise an inner layer (1,4) and an outer layer, (3,7) both being liquid- and air-impermeable. The outer layer (3,7) is sealed to the inner layer (1,4) so as to surround a zone of the inner layer (1,4) which is not sealed to the outer layer (3,7). The space (11) between the layers in the above-mentioned zone is free of air, and the outer layer (3,7) is translucent or transparent in the area overlying that zone and having a contrasting colour relative to the colour of the inner layer (1,4), so as to provide a visual indication (a change in the perceived colour) when the outer layer (3,7) is breached, as a result of tampering, accidental damage or the like. |
