Sneaking Suit

The Sneaking Suit is a special outfit designed specifically for infiltration missions. It was created with electronic spinning technology using optic fibers. By clinging to the wearer's body, it protects internal organs and boosts strength. It also blocks harmful elements, is equipped with various sensors, and can interact with nanomachines. It is the standard field uniform used by Solid Snake, as well as other FOXHOUND operatives.

History
The earliest known Sneaking Suits were developed by the Soviet Union. One of the suits, a white prototype, was worn by The Boss during Operation: Snake Eater after she defected to the Soviet Union and joined Colonel Volgin's ranks. The second prototype, a black suit, was uncovered by Naked Snake in the locker room of Groznyj Grad.

The suit found by Snake was then brought back to America and reverse engineered by the FOX unit, eventually making it their standard issue uniform. This variation of the suit was known as the Close Quarter Combative Enhancer suit and it improved the wearer's hand-to-hand skills. It was worn by Naked Snake, as well as key members of FOX during the unit's revolt in 1970 during the San Hieronymo Takeover.

Solid Snake wore an official sneaking suit during the Shadow Moses island operation. This suit was specifically designed to withstand harsh winter environments and prevent hypothermia. It would go on to serve as his uniform during his exploits with Philanthropy (without its thermal vest or elbow/knee pads); seeing Snake through on the Tanker Discovery a small portion of Big Shell and Arsenal Gear.

The sneaking suit worn by Raiden during the Big Shell operation was known as the Skull Suit due to its design. Its design consisted of water-repelling scales that allow the wearer to swim easily, and had a pebbled texture -- the principles of which were not unlike that of a golf ball (i.e., to reduce drag).

The sneaking suit worn by Solid Snake (now codenamed "Old Snake") while he hunted Liquid Ocelot in 2014 was equipped with a state-of-the-art camouflage system called Octocamo, in addition to minimizing noise and slightly enhancing user strength, which came in handy as Snake's body strength had deteriorated somewhat due to the accelerated aging he suffered from. This particular sneaking suit was completely ruined in the process of protecting Snake from a hallway full of microwave emitters aboard Liquid's personal flagship, Outer Haven.
