Arctic Batgirl suit

The Arctic Batgirl suit is a protective, almost completely bulletproof and blade proof, as well as completely fireproof suit and combat armor developed by Alfred Pennyworth, Barbara who uses it for fighting crime during her activities as Batgirl. The Arctic suit or ice armor suit were constructed to protect Batman, Robin and Batgirl from the freeze blasts of Victor Fries. They may also help keep body temptature up in a cold environment. The silver pieces are presumably made out of the same material that the Bathammer hull is composed of, to reflect ice blasts.

Functions

 * Identity concealment: The primary use of the suit is to conceal Barbara's identity in order to prevent enemies from knowing her true identity while still being able to operate as a vigilante.
 * High-density kevlar armor: The suit is composed of a kevlar-based material with a leather appearance. Its durability is first shown to be dense enough to take one of Joker's bullets to the chest, albeit the bullet did manage to penetrate the suit's armor, though not enough to injure Barbara. The armor was later upgraded, now being able to protect Barbara from gunfire at point-blank range, as well as from impacts that would otherwise be severe and possibly fatal.
