A stealth suit was a type of clothing developed and used by Starfleet Special Operations in the mid 23rd century. The stealth suit was a full-body outfit, including a face mask, which was able to mask body heat in order to avoid infrared detection. Colored black, the stealth suit allowed the wearer to go largely undetected in shadows and other dark areas.
In 2265, Jaeq, an associate of Orion merchant prince Ganz, used a stealth suit in order to kill two Starfleet officers and assault a third on board Vanguard. (SCE eBook: Distant Early Warning)
- The stealth suit could be considered an early precursor to the 24th century's isolation suits.
