The Flash suit is a protective scarlet suit bearing a golden lightning bolt design on the chest, worn by Barry Allen as the Flash to hide his identity from his enemies when he fights crime.[1]



"Silica-based quartz and fabric. Abrasion resistant. Heat resistant."

Barry Allen created the suit from a sophisticated anti-friction material to protect himself when running at superhuman speeds. The suit is composed of silica-based quartz and fabric, with Bruce Wayne noting that it is the same composite material that NASA uses to protect spaceships during reentry, in order to avoid burning up from the immense air friction encountered when Barry runs, as well as being cold resistant, in the event that it's exposed to extreme temperatures.[2]

Knightmare Suit

In an alternate future where Superman becomes a malevolent tyrant opposed by Batman and the Insurgency, Barry Allen wore a mechanically altered version of the suit that was more armored and streamlined, while also having a retractable helmet that covers Barry's head and face, while a more traditional cowl was worn underneath it.[3] The base of the suit bore a pearlescent sheen to it, while the plated armor is layered, allowing full range of motion while also protecting the wearer.

Behind the scenes


  • Unlike the suit from the DC Comics universe, this version isn't a singular piece of protective material, instead it's made from a collection of pieces bolted together.
  • The suit seems to take inspiration from its counterparts seen in the Injustice universe, as well as the suit seen in the DC Universe Online game, serving as a more functional piece of 'armor'.
  • The Knightmare suit bears a resemblance to the Flash's Earth-1098 counterpart.

Behind the scenes

  • According to Jason Momoa, Flash actor Ezra Miller has to have the suit screwed together onto him.[citation needed]
  • In total, the suit is comprised of approximately 140+ individual pieces.[citation needed]
