📋 About This Mod
Before the Institute had advanced gen-3 Synths to do their delicate surface tasks they had to send real humans above ground to conduct research by hand, and to protect such agents they developed the The Institute Expeditionary Suit (IEX). The IEX suit is the pinnacle of wasteland utility, providing armor and resistances against the harsh wastelands.
The base outfit itself is enough to completely neutralize minor radiation hazards from shallow water, and when worn with all items of the set provides near total immunity to radiation on par with industrial hazmat suits. A special context menu that can be accessed by equipping the outfit while in pip-boy mode will allow you to swap outfit styles anywhere any time, without the need for an armor bench.
The IEX mask acts as an advanced gasmask, light source, and is a platform for advanced tech modules, which can help an Institute agent navigate the less friendly elements of the wasteland. In addition the mask can be attached to the base outfit's belt when not being worn.
