Based on the SEIE MK11 Submarine Escape Immersion Ensemble design, the MK11 Jerkin has been designed for instances where storage space is limited onboard a vessel. The MK11 Jerkin is particularly suited to submariners operating in temperate climates where thermal exposure is limited. Manufactured from lightweight, durable polyurethane-coated fabrics the MK11 Jerkin consists of a sleeved waistcoat assembly, an inflatable stole complete with two pressure relief valves and an integral ascent hood. The improved comfort, fit and functionality of the MK11 Jerkin bear witness to its substantially improved design.
