Elder Lyons' Robe

Elder Lyons Robe is the robe Elder Lyon wears believe it or not. These robes are glitched because there picture in your Pip Boy displays the Vault 101 Jumpsuit. When you drop these robes they also look exactly like the Vault 101 Jumpsuit. On top of this, if you equip these robes they will cover up your Pip Boy unlike all the other clothes/armors. This robe was never intended to be wore by a character with a Pip Boy so that is why it most likely covers it.

To get these robes you will need a stealth boy (sometimes to help for hiding) and a set of armor that has a DR of something greater than 5 I would say. Once you have these items find Elder Lyons and go into sneak mode (make sure it says 'Hidden'). Reverse pickpocket that set of armor/clothes you brought with you onto him and then leave the area you are in. Return back to the area and Elder Lyons will be wearing the item you just placed onto him thus allowing you pickpocket his robe.

This was tested on the ps3 reverse pickpocketing a set of Talon Combat Armor onto Elder Lyons, and it worked.
