MK 44 - Life Preserver


The Mk44 Life Preserver is primarily intended for use by helicopter crews, but it is equally suitable for use in fixed-wing aircraft. It comprises a fully adjustable waistcoat and is available with either a single-chamber or a twin-chamber inflatable stole, which is contained within a protective pouch.

The front of the waistcoat and the stole pouch are manufactured from breathable, flame-retardant fabric. The back of the waistcoat is manufactured from mesh fabric to reduce heat discomfort and fatigue.

Used for a range of applications, the Mk44 Life Preserver is one of the most popular lifejackets on the market and is preferred by a large number of the leading commercial helicopter and oil and gas operators worldwide.
