Work clothes worn by soldiers or military personnel, designed for durability and camouflage; or extreme tiredness.
From French 'fatigue,' derived from 'fatiguer' (to tire), which may come from Latin 'fatigare.' In military context, 'fatigue' referred to non-combat work, and 'fatigue clothes' were practical wear for such labor. The plural 'fatigues' became standard for the garment itself.
