XS suit

The Flash suit, known in the future as the XS suit, is a protective suit that Iris West wore as the temporary meta-human known as the Flash and that later would be adopted by her daughter Nora West-Allen.

Original 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.

Upgrades
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.
