A free mod for Fallout 4, by Niero.

This is a mod that makes it possible to equip your character with a special kind of armor, called the Institute Expeditionary Suit (IEX). This is an important piece of equipment for nuclear safety, and is used by the Institute to protect its agents. It is made of a highly durable metal that is used for research and contains an advanced gas mask, light source, and a platform for advanced tech modules.

The IEX mask can be worn as an accessory to the base outfit, and can be used as a temporary armor and weapons during a deadly storm. It can also be equipped with a wide variety of weapons and modules, including a variety of armor, tools, and weapons.

When the IEX mask is worn, a special context menu is accessible, which can be accessed by clicking the icon on the bottom left of the screen. The menu will allow you to swap the current outfit style with any other style you wish. The menu also contains information about the current location, and a map of the area.
