Armored Valentine Trench Coat
Valentine is my favorite companion in Fallout 4 and it kind of irked me that I could modify other companions default outfit with Ballistic weave but Nick was left out due to not being able to exchange his outfit. So using Fo4Edit I added resistance modifiers to his coat in order to have him wander around with me, being able to take a bit more of a beating, while keeping his PI theme intact.
The Coat now sports a ballistic armor rating of 100 and an energy resistance rating of 100. 10 points lower than maxed out ballistic weave.
