As his superhero alter ego the Flash, however, Barry wears a form-fitting red suit that covers his entire body and head. It has a fitted face mask that covers his head, but leaves his mouth and eyes exposed, with there also being wing-shaped earpieces. His body is covered entirely with protection pads scattered across the suit in various places, such as the torso, to better protect Barry, with the joints areas free for movement so he can run with little restriction. There is a white circle with a yellow lightning bolt in the center of the chest.

The Flash suits are a series of protective suits designed and created by Cisco Ramon at S.T.A.R. Labs, and Ryan Choi sometime in the future. Originally designed to replace the turnouts firefighters, the suits are now used by Barry Allen for his vigilante activities as "the Flash".

The Flash ring is a ring owned by Barry Allen that is used to store his Flash suit. It bears a lightning bolt symbol similar to the one sported on the chest piece of the Flash suit.
