The mask is made of a butyl style rubber, with a textile head harness. There are only three pieces of visible stainless steel on the mask, the input clamp band, and the two screws holding the exhale valve/voice diaphragm cover on the main structure, the rest is rubber and tough gloss and flat black plastic. SanCheong is printed on the fore-head, along with a size indicator on the right fore-strap.
The threading is STANAG 4155 compliant, allowing standardized NATO canisters to be used. A large metal band seals the rubber around the front assembly, and can be taken off with the access of the lower clamp.
The eyepieces are triangular. Like most masks of this era, it has an inner second seal, along with an oral-nasal cup with two inlet valves.
The mask uses a completely fabric head harness with a large comfortable mesh skull cap with a small pull tab on the bottom. It uses plastic buckles.
