This pair of Roman style leg greaves offer complete leg protection for re-enactors.

A greave (from 12th century French greve "shin", of uncertain origin) is a piece of armour that protects the leg.

Often in matched pairs (a pair of greaves), greaves may be constructed of materials ranging from padded cloth to steel plate - as here. Some designs protect only the lower leg (a half-greave) or extend upwards to protect the thigh

Better equipped Roman Republic soldiers, Triarii, wore greaves on both shins reminiscent of the Ancient Greeks.  The Roman Centurions wore altered greaves from the standard Roman uniform. Later Imperial Legionnaires did not wear greaves, except for the centurions who retained them.
