The Interlock 275 is specially designed for use as a combined working/abandonment life jacket. It is designed to be worn when the user is wearing heavy duty clothing or with an abandonment suit.

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

With 330N buoyancy performance the life jacket 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 patented interlocking lobe design also creates an effective wave barrier, preventing water channelling into the airways.
