Gauntlets of the Dragon (3.5e Equipment)
From D&D Wiki
Gauntlets of the Dragon: These gauntlets are composed of black dragonhide with dragon claws and an etching of a dragon lifting a large sword.
Wearing these gauntlets allows the wearing to wield weapons up to colossal size as though they were sized and weighted for the wearer.
For the purpose of unarmed attacks, consider these gauntlets as normal spiked gauntlets.
