A protective suit of armor was worn by the time remnant of Barry Allen known as Savitar. Barry briefly wore the armor himself during their confrontation. It was later destroyed by Barry Allen during Savitar's last stand.
Unlike other speedster suits which are typically made of a heat-resistant leather-like material, Savitar's armor is completely metallic, and also covers its occupant from head to toe. The inside of the suit, such as the rib cage area and the eyes, seem to glow a light blue color if Savitar is inside it, although a red color was emitted when Barry took the suit. Like the suits of the Reverse-Flash and Zoom, Savitar's suit bears a downwards-pointing diagonal lightning bolt symbol on the chest. The mouth of the suit can open as if an actual mouth, and there are two retractable blades at the wrists.
The suit also has the extra function of acting as a protective armor. Due to the immense charge Savitar generates while running the suit was made to protect him from the static build up he creates while moving at super speed.
The user must enter and exit the suit by bending over, as the suit opens up so they can step in and out.
The suit gives its wearer speed as the wearer gives off static electricity. 
Tracy Brand has a theory that Savitar gives off so much speed and power when he runs that the suit protects him and keeps it from overwhelming him.
It is later discovered that either the suit has a mind of its own, or Savitar can remotely control it, moving even when no one is inside it. It also appears that the armor itself gives Savitar white lighting, as it was shown before he jumped back into it that he still had yellow lightning when he uses his speed.
It is possible for a speedster from the outside to phase into the armor and force out the previous bearer in the armor just as Barry was able to eject his time remnant out, the blue light coming from the suit also changed color from blue to red.
- Advanced durability: The armor itself is extremely resilient and enormous durability, enough that Joe West's bullets and shots from the Mercury Labs Energy Rifle ricocheted off him harmlessly. He also takes nearly no damage when The Flash or Wally West attacked him, although he was shown to feel pain when The Flash severed his arm blade with his vibrating hand and Jesse Quick stabbed the armor with the severed arm blade. However, as his suit has been shown to be removable, it's possible that was a reaction to discomfort. So far, he has only been damaged by weapons made from its own material.
- Advanced strength: The armor's size, mechanized parts and material give it great strength, allowing Savitar to effortlessly lift, drag and send people flying through the air with one hand. Even when his briefly lost his memories and, therefore, forgot his powers along his younger self, he retained his strength due to his suit, allowing him to lift Caitlin Snow against a wall with one hand. While operating without Savitar being inside it, the suit managed to throw the younger Flash several feet and briefly pin him down with its foot before the speedster forced it off him.
- Armor retraction: Should any part of his armor be broken off, it can immediately be drawn back to Savitar from any distance, to the point where any broken off pieces can be telekinetically summoned back to the rest of the suit if it is close enough.
- Cold resistance: The armor protected him from Caitlin Snow freezing him solid, as he was able to instantly burst out of it unfazed and ran away instantly in the speed of a lightning bolt.
- Hidden blades: Savitar is able to retract a hidden blade from his wrists as melee weapons.
- Mental connection: To a certain degree, the armor can move and attack on its own, should Savitar be attacked out of his suit, though it is unable to use Savitar's speed.
- Static charge displacement: The armor's primary function is to shield Savitar from the highly dangerous levels of static charge built up whenever he uses his advanced speed.
- Voice filtering: Savitar is able to disguise his voice so as to not be identified as a megalomaniacal version of his past self. This only applies to Savitar, as the original Barry just sounds echoed in the suit.
- Armor coloring: Depending on which speedster is in the armor, the glowing parts will change corresponding to the bearer. For Barry, the glow was red while his time remnant had a blue glow. Also, the armor is capable of changing the color of a speedster's lightning as the armor changed Savitar's lightning from yellow to white. As Barry did not run inside the armor, it is unknown what color his lightning would be.
Behind the scenes
- Up until "The Wrath of Savitar", the suit and Savitar himself were completely CGI, before later mostly being replaced with a practical suit. The CGI is still used for when Savitar is running and for the scene in "Infantino Street" when he murders Iris.
