The Simon Gauntlets are black metal gauntlets covering Enma's forearm. In the back of the hands, it has a red hexagon emblem with a crosshair in the middle, similar to Enma's eyes. It is also surrounded by rings of text.
After the Simon Rings were upgraded by the Vongola Sin, the Simon Gauntlets have changed in appearance. On one side of Enma's arm, the gauntlet went further up his arm, extending to his shoulders while forming a wing-like armor on his shoulder. On the other side, it changed to have the Simon Famiglia emblem on the center of the back hand.
The gauntlets can be used by Enma as a medium to manifest his Earth Flame, creating spheres of dense gravity around opponents. Similar to the Tsuna's X-Gloves, the gauntlets can release Flames for propulsion and levitation.
The gauntlet's abilities of gravitatial manipulation increased even further after being upgraded by the Vongola Sin, shown during Enma's temporary fight with Tsuna.
