105 MK1 Infant Lifejacket

Specialised Safety for Infants in Emergency Water Landings

The 105 Mk1 Infant Lifejacket is a dedicated flotation solution designed specifically for infants, building on our five decades of expertise in aviation safety and over 1 million lifejackets produced. As the trusted supplier for the world’s largest aviation organisations, the infant lifejackets ensure the safety of even the youngest passengers during emergency water landings.

The 105 Mk1 is a single-chamber lifejacket, CAA-approved, and designed to position the infant face-up in the water, providing critical support even in the event of unconsciousness. This specialised infant version also includes additional safety features such as an integrated harness for lifting and a lifeline for securing the infant to an adult or survival liferaft.

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.
