Underarmor refers to a type of garment designed for wearing together with power armor of various types, meant to increase the comfort of the operator when wearing the outfit for extended amounts of time.
The T-45 power armor model is designed for a single operator and is patterned closely after the human silhouette. It consists of three layers. The first is a black body suit worn by the operator for comfort, insulation, and protection from injuries that may be sustained during the armor's operation. The second layer of the armor is part of the power armor proper. These two are commonly referred to as recon armor when worn together. They form a full body suit made of thick, processed fabric with integrated metal plating that serves as a platform for attaching the armor and on-board hardware. The recon armor is, in effect, the underlying chassis of the T-45 power armor model. Its attachment points and power cell plug at the nape of the neck are essential for the operation of the full T-45 power armor, as the third layer consists of the armor, the fusion power cell, as well as the hydraulics and servomotors that allow the operator to carry heavy ordnance into combat and bear the weight of the armor.
This armor was replaced by the universal power armor frame and matching jumpsuit. However due to the ongoing War it was never completely decommissioned, repurposed as a recon variant of the standard T-45 power armor, without the external armor plating, but increased mobility.
Designed from the ground up for use in conjunction with the West-Tek power armor frame, the next generation underarmor is a form-fitting suit designed for maximum comfort and utility while operating the armor. Although it (or the hood) is not a requirement for operating the armor, it makes long-term use more comfortable and reduces chafing. The hard points and attachments on the suit also improve performance, interfacing directly with the armor's systems. The suit wasn't designed for use outside of armor: It features only two pockets on the hips for documentation and maps and a simple flap over the crotch. Its comfort and lack of bulk allow the operator to combine it with a variety of tactical gear and protection, for example, combat armor.
Behind the scenes
- Both the recon armor and the uniforms are internally coded and referred to as underarmor. Whether this is a retcon or evolution of the design is not certain.
- The underarmor would serve as basis for the armors of Kells, Arthur Maxson, and likely Cade. The assets still remain in the files and can be seen below:
- Owyn Lyons: "Scribe Bowditch, I trust you are well. I'm here for your progress report on the modified Recon Armor."
Bowditch: "Ah... you're a bit early today, sir. Regardless, I'm happy to report that the development of the Mark II Recon Armor unit is proceeding as planned."
Owyn Lyons: "I'm pleased to hear that. Do you anticipate any setbacks? Last month's progress was, well... let's call it "underwhelming.""
Bowditch: "There may be a slight delay in the enhancement of the ambulatory gyroscope. A few of the parts I need were lost in the recent... inventory reduction."
Owyn Lyons: "You'll make do, Bowditch. You always do."
Bowditch: "Thank you, sir. I appreciate it."

Form-fitting suit meant to be worn while operating power armor. It has a variety of hard points and attachments for interfacing with a PA frame. This suit isn't necessary for using power armor for short stints, but it facilitates more comfortable long-term use (and has less risk of chafing)."
