MK44 Crew Lifejacket

Advanced Protection for Helicopter and Fixed-Wing Crews

The MK44 Crew Lifejacket is designed for use by both helicopter and fixed-wing aircraft crews, offering robust safety and comfort in critical situations. With a fully adjustable waistcoat and the option for either a single or twin-chamber inflatable stole, the MK44 ensures flexibility based on mission requirements. This lifejacket is lightweight, allowing for maximum manoeuvrability, and is compactly contained within a protective pouch for ease of use.

Constructed with flame-retardant materials and a mesh back, the MK44 reduces heat discomfort and fatigue, making it the ideal choice for crew members facing high-risk environments.

Performance

In aviation, performance means more than function, it means readiness under pressure. Our lifejackets and crew safety systems are engineered for rapid deployment, reliable flotation, and operational endurance across both civil and military platforms. Whether supporting commercial aviation or tactical flight operations, they deliver consistent, trusted performance when it counts.

Innovation

We advance crew safety through continuous innovation in design, materials and survivability technology. From lightweight lifejackets for civil aviation to high-performance systems for rotary and fixed-wing aircrew, our products are shaped by real-world feedback, evolving regulatory requirements and a commitment to continually raising the standard in aircrew protection.

Protection

Crew protection is central to safe and effective aviation. Our life-saving systems are designed to perform in high-stress, high-consequence environments, providing flotation, thermal protection and secure fit across a range of mission and commercial profiles. Certified and rigorously tested, they help protect lives at altitude, on approach, or in emergency descent.
