• Product Code: Alpha 275N 3D TWZ TWIN
  • Availability: Pre-Order


solas approved inflatable life jacket

  • SOLAS premium model: high volume, twin chamber 3D technology. 
  • SOLAS lifejacket/lifevest certified to IMO Res. MSC.81(70) amended by MSC.200(80) and MSC.207(81).

This design combines two important innovations in lifejacket technology. 

The patented buoyancy chamber design is built with a double inflatable chamber so for extra safety, the second compartment can be filled by a simple tug on a cord to manually operate the CO2 cylinder, thereby maintaining the full buoyancy. 

Also, the 3D design provides considerable buoyancy on the front chest area, offering much enhanced righting moment to any unfortunate casualty in the water, turning them quickly onto their backs – very important if wearing heavy foul weather clothing or a tool belt. 

Because of the three-dimensional design, the visibility of the wearer in the water increased significantly and allows the installation of an emergency light at the highest point of the buoyancy chamber and approximately 20 cm higher than traditional life jackets. 

  • Also a PLB in this position offers a significantly improved transmission range. (optional) 
  • Available with different accessories such as harness and emergency PLB.

Lifejackets need a service too

Where the safety of peoples’ lives is concerned, regular inspection of the equipment concerned is absolutely essential. This also applies to lifejackets. Natural aging process can influence the properties of the material and also the functioning of the automatic inflator system is not immune to possible damage (among other things operational errors). In other words: the life of a lifejacket must be limited. The corresponding time frame has been set at 10 years, a decision borne authoritatively by the members of the German Association for Sea Rescue Equipment (FSR), and which complies with the law of safety and product liability.

A prerequisite for this lifetime is an inspection of the lifejacket by an authorized servicing station or the manufacturer at least every two years.

Safety as a visible sign

Regular inspection is documented by the FSR-Service-Sticker, which, similarly to a car’s MOT sticker, signalizes the month and year of the next service due.


The regular system check by the expert comprises testing the buoyancy chamber for air leaks as well as a scrutinizing check of the fully automatic inflation system. Moreover, within the framework of this SERVICE we can offer:

  • Repair
    Removal of any defects discovered in the course of the inspection as well as replacement of the complete protective cover or buoyancy chamber.
  • Conversion / Optional extras
    Converting from manual release to automatic inflation, adding a spray hood, installation of an emergency light and further signalling accessories.

Receipt of the new FSR-Service-Sticker confirms, so to speak, the correct functioning of the rescue equipment and always reminds you of the Date of the next inspection, the sticker being clearly visible from the outside.
