Sneaking Suit

A sneaking suit is a suit that has been used by many soldiers throughout the Metal Gear Solid series. The suit is nearly skintight, and contains many holsters to hold weaponry.

Origin
One of the first sneaking suits was discovered during KGB testing by Naked Snake during Operation Snake Eater. Though the suit was clunky and unsightly, it reduced all damage inflicted by half and prevented Snake from losing stamina otherwise. During the mission, Snake suggests that the suit become the official uniform of the FOX unit.

By 1970, the suit had gone through many changes, becoming tighter than the original but still attaining much of the same functionality. The suit was used by Big Boss during the events of Metal Gear Solid: Portable Ops.

Nearly 35 years later, the sneaking suit had not changed much, with no major visible changes seen on the suit used by Solid Snake during the Shadow Moses incident. Snake used a similar suit during the Tanker chapter and Big Shell incident. At about the same time, the operative Raiden was using a skull suit, a similar piece of equipment that was apparently even tighter and slightly different in appearance. The suit was a procurement of the Patriots for Raiden to use during the Big Shell incident.
