Equipment overvests were a type of garment, specifically clothing, that the rebel pilots belonging to Gray Squadron wore on top of their pressurized g-suit overalls. These overvests integrated a backup breathing system that could connect either to the pilot's starship or function on its own for a certain time period. During the Battle of Endor in 4 ABY, pilots such as Ekelarc Yong and Gureni Telsij utilized equipment overvests.
The initial appearance of equipment overvests was in the 1983 original trilogy movie, Star Wars: Episode VI Return of the Jedi. Their identification occurred for the first time in the twenty-sixth issue of the Star Wars Helmet Collection, which saw its release in 2016.
