The SOLAS approved Challenger Interlock 275 lifejacket in durable red Nylon fabric has been designed for use as a combined working/ abandonment lifejacket. This incredibly lightweight and comfortable to wear lifejacket design gives excellent neck and head support which is particularly vital for an unconscious wearer.

With 300N buoyancy performance, the lifejacket is designed to be worn when the user is wearing heavy duty clothing or with an abandonment suit, where it guarantees to self-right the wearer in less than 5 seconds. The interlocking lobe design also creates an effective wave barrier; preventing water from channelling into the airways.

It features a durable red nylon cover with hook and loop closure making it easy to re-pack once activated. The operating head is easily accessible and can be checked when required. Challenger Interlock lifejackets are now available with AIS 'Recovery System' integration.
