The mesotoga is a rare and powerful piece of clothing in Dragon Quest IX. It is one of the final forms of the tropotoga. Despite its description, it protects the wearer from all elemental attacks, not just fire and ice.
The mesotoga is named after the mesosphere, the third layer of the atmosphere and the one above the stratosphere. It and the rest of the togas in its line are named after the various layers of the Earth's atmosphere.
