- For the Flash suits worn by other characters, see The Flash suit.
Initially, Iris used the suit's jacket as normal apparel.
After Matthew Kim transferred Barry Allen's DNA to Iris's body, she gained Barry's powers. When there was a fire in Central City, Cisco gave her a spare mask belonging to Jesse Wells in order to conceal Iris' identity.
When Jaco Birch started attacking Central City with his newfound pyrokinetic powers, Cisco modified Iris' jacket presumably to become friction-proof. After she apprehended Birch and Matthew restored Barry's powers to his body, Iris stopped using the suit.
In the future, Iris will eventually pass the suit onto her daughter Nora. The suit had a XS insignia. She used the suit when assisting her father in destroying a satellite, and later as normal apparel.
Unlike Iris's version of the suit, this version has the symbols Barry wrote after his time in the Speed Force as a pattern on the suit.
