You can only obtain Assaults Vest at the Battle Maison’s Exchange Service Corner in exchange for 48 BP. The Assault Vest is a held item that raises the holder’s Special Defense by 50%, but it prevents the holder from using status moves.
Ever since its introduction in X and Y, the Assault Vest has been widely used in a lot of competitive teams. It’s great on a wide variety of Pokémon as its benefit is usually worth the cost.
Equipping an Assault Vest on Pokémon with naturally high Special Defense like Goodra can make them very difficult to get rid of.
On the flip side, the Assault Vest also works well with Pokémon that aren’t naturally Specially Defensive. A 50% boost is significant enough to make your Pokémon take more hits than it would have.
To make up for being unable to use Status Moves, be sure to have your Pokémon learn a wide variety of moves for good coverage.
