This mod is pretty simple. It adds new suits and each suit can have your normal armor pieces equipped!To keep the excellent look of the suit, You should use the mod Concealed Armor.
There is the normal one, with a cleaner helmet. One where you can have your hair visible in the helmet (can cause clipping depending on the hair style). A functional Rocket version of each of the above.
The default ability of the suit is that it adds +1 Charisma and breathing under water. With my no Helmet versions, you won’t be able to breathe under water haha. But you will gain an extra +1 to Charisma and +1 to Perception.
Requires Nuka World DLC
