Abstract: The present disclosure relates to a variable helmet that can be unfolded flat and carried or kept when not in use. A configuration of the variable helmet is characterized by including a protective pad in which a plurality of unit pads are planarly coupled like a mosaic so that the protective pad is in a hemispherical shape to cover and protect a head of a wearer and is able to be unfolded flat like a plate, the protective pad having unevenness portions provided in a sawtooth shape at both ends thereof; both-end fixing means allowing the unit pads to have a hemispherical shape by tightening the both ends of the protective pad; and a chin strap allowing the protective pad to be fixed in a state in which the protective pad is covered on the head.
