A First Order stormtrooper, covered in a body glove, is putting on their stormtrooper armor.
A body suit, which is also known as a body glove, was a skin-tight, full-body garment. Clone troopers serving the Galactic Republic, stormtroopers of the Galactic Empire, stormtroopers serving the First Order, and Sith troopers from the Sith Eternal all wore black body gloves underneath their protective armor.
The phase I armor used by clone troopers, which had temperature regulation, was secured to twenty plates made of a plastoid-alloy composite through the use of magnatomic gription panels that conformed to the body. The pressurized body gloves they wore also provided the clones with short-term protection from the vacuum of space.
