Gladiator helmets, made of bronze, were much heavier than the helmets the Roman infantry would have worn and therefore less likely to be seriously damaged. Roman gladiators generally wore helmets (with the notable exception of the Retiarius who was equipped with a net and trident), arm and leg guards, and some had shields. The horseback Andabatae had body armor. The helmets partially (or in the case of the Andabatae, completely) obscured the gladiator's vision.
