The Flash Suit is the protective scarlet suit, bearing a golden lightning bolt design on the chest, which is worn by Barry Allen as his superhero alter-ego, the Flash, to hide his identity from his enemies when he fights crime.
Barry Allen wears a protective scarlet suit (with quite a few wires holding the various pieces together, and a golden lightning bolt design on the chest) as his superhero alter-ego, The Flash, to hide his identity from his enemies when he fights crime. The suit is composed of specific fibers, with Batman noting that it is the material that NASA uses to protect spaceships from burning up as they re-enter Earth's atmosphere (in order to avoid the suit burning up from the immense air friction created when Barry runs at super-speed).
Barry Allen's second more updated suit, made for him by Batman. It is slightly similar to Bruce's suit though it's armor plated and overall heat resistant.
