Mission Oriented Protective Posture

Mission oriented protected posture (abbreviated "MOPP", pronounced "mop") is a term used by the Federation Starfleet personnel to describe protective gear, often worn off-world when SG teams find themselves in an environment that could be harmful or toxic. It should not be confused with the Hazmat suit, which has a similar function.

SG teams carry the MOPP gear in their packs, and are usually seen wearing or applying only the gas mask, however, there are at least four levels of MOPP protection.
