you could edit the .xml, or remove it entirely.
location is the Steam folder..
\SteamLibrary\steamapps\workshop\content\294100\1814988282\1.3\Defs\ThingDefs_Misc

294100 is Rimworld
1814988282 is Vanilla Armour Expanded
1.3 is specifically Rimworld 1.3. If you use 1.2, go to the 1.2 folder instead.

In this folder you will see Armor_Spacer.XML
You could edit it, delete it, or the easiest and safest method would be to rename it so it's no longer read into the game. This requires you to rename the file extension,

ie: Armor_Spacer.XML.txt

Spacer armour defs will vanish, it will no longer exist in the game. You can undo this by reversing the filename change. As far as a simple solution goes, this would work. It may throw an error the very next time you open the game. Others may criticise this and present a better method to you

I just deleted it. Worked like a charm. Thanks

Of all the armours, not sure why you would want to remove that one. It only covers the middle layer, allowing you to wear a low-cost outer layer for warmth, items such as capes for ideoligion roles, or eltex robes without sacrificing quality defence and movement speed. Personally, I find prestige trooper armour to be the ideal option for combat psycasters, and where affordable, I use it for all of my armed colonists as a standard armour.
