This is the leather Mantis Armor (Mantis Left Greave and Mantis Left Armguard) re-colored black. Depending on what mod you are using on your armor it will look slightly different. Enjoy!
1. Place the texture folder into C:\Program Files (x86)\Steam\steamapps\common\Fallout 4\Data. If you already have the texture folder, place the contents inside into the folder.
2. Open the Fallout4.ini file in your Documents folder: (…Documents\My Games\Fallout4) and find the line: sResourceDataDirsFinal
Replace it with: sResourceDataDirsFinal=STRINGS\, TEXTURES\ and save the file!
