The Mantello di Vongola Primo is a cloak initially used by the first generation Vongola Boss, Giotto. Through the future Vongola technology, the 10th generation Boss, Tsuna, is able to use this weapon through his Box Animal. The cloak has the Roman Numeral "I" on the front to symbolize the connection to the Vongola Primo.
The cloak has the ability to nullify attacks using the Sky Flame's Harmony characteristic. The Sky-attribute of the cloak even has the ability to turn Box Animals into stone.
After unlocking the Original Vongola Rings, the metal band of the cloak with the Roman Numeral I gains several sharp spikes.
