The MK-Compression Suit is a space suit variant worn by the crew members of the USCSS Nostromo.
These suits are used by the Nostromo's crew to work and survive in low-pressure environments. The suits consist of at least three variants, the brown and yellow colored suits which both are used for exploration, while the completely white-colored suits are used for emergency situations.
Small lamps are fitted on top of each suit's helmet, however this feature is absent on the white-colored suits. Aside from being equipped with oxygen tanks, the suits are also equipped with handy tools such as flashlights, grappling guns, laser pistols and communication devices which are used to keep in touch with the other crew members, as well as the Nostromo.
