The Flash

"Silicon-based quartz sand fabric. Abrasion resistant. Heat resistant."
"Uh, yeah, I do... competitive ice dancing."
"It's what they use on the space shuttle to prevent it from burning up on re-entry."
"I do... very competitive ice dancing.

Barry Allen wears a protective scarlet suit (with a number of wires holding the many pieces together) emblazoned a golden lightning bolt design on the chest as his superhero alter-ego, the Flash, to protect himself from friction encountered when running at super speed, as well as hide his identity. The suit is composed of silicone-based quartz sand fabric, with Bruce Wayne noting that it is the same composite material that NASA uses to protect spaceships during re-entry, in order to avoid the suit burning up from the immense air friction encountered when Barry runs at super speed, as well as being cold resistant, in the event that it's exposed to extreme temperatures.[2]

Knightmare Suit

In a seemingly alternate reality where Superman became a malevolent vengeful tyrant, opposed by Batman and the Insurgency in the Injustice War, Barry Allen wears a mechanically altered version of the suit. This suit is more armored and streamlined, probably to protect from Parademons , and maybe even Superman himself, while also having a retractable protective helmet that covers Barry's head and face, while the traditional cowl is underneath i.t[3] The base of the suit bears 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, the suit used by Barry Allen 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'.
  • In the comics, the suit is completely red.
    • Fans have had a negative reaction to the fact that it isn't a single red suit, like the one seen in its CW counterpart.
  • The Knightmare suit bears an uncanny resemblance to the Flash's Earth-1098 counterpart.

Behind the Scenes

  • According to Jason Momoa, Flash actor Ezra Miller has to have the various pieces of the suit screwed together onto him.
  • In total, the suit is comprised of approximately 140+ individual pieces.
  • Before the release of Justice League, it was rumored that Barry would receive a new suit made by Bruce Wayne, but this ultimately did not happen.
