Spinlock DURO SOLAS 275N Lifejacket
Best high-buoyancy safety gear for commercial maritime professionals working in demanding conditions.
This is the Spinlock Deckvest SOLAS Twin Chamber 275N lifejacket, a robust flotation device often required for commercial use in demanding environments like wind farms, superyachts, and oil rigs where SOLAS approval is mandatory. It features a twin chamber design providing 275N of buoyancy. It's specifically designed to fit comfortably over most fall arrest harnesses and workwear, offering freedom of movement without excessive bulk thanks to its structured shape and unique bladder design that supports the body in the water. Inflation is automatic via two UML Mk 5 inflators, each using a 60g CO2 cylinder activated by a water-sensitive system that prevents accidental firing from spray or rain. The Pro Sensor inflators provide visual status indicators for the CO2 cylinder and firing head. This lifejacket comes complete with an included Pylon™ Lifejacket Light and has provisions for attaching an optional sprayhood and a Chest Pack. It also integrates with the AIS MOB1 unit and is compatible with Lume-On™ lifejacket illumination lights. It is approved to the latest 2010 SOLAS Standard and CE ISO12402-2.

Know before you buy
Yes, it is specifically engineered to be worn over most standard fall arrest harnesses. Its structured shape and low-profile design ensure it remains comfortable and allows for full range of motion while working.
The twin chamber design provides redundancy. If one chamber fails or is punctured, the second chamber still provides sufficient buoyancy to keep you afloat, which is a critical safety requirement for commercial and offshore environments.
No, the UML Mk 5 inflators are designed with a water-sensitive system that requires full immersion to activate. They are specifically calibrated to ignore heavy rain, spray, or humidity, preventing accidental inflation.
The lifejacket features Pro Sensor inflators with clear visual status indicators. You can easily check the status of both the CO2 cylinder and the firing head through the inspection window without needing to unpack the lifejacket.
Yes, it comes with a Pylon™ Lifejacket Light included and is designed to integrate with an AIS MOB1 unit. It also has attachment points for an optional sprayhood and is compatible with Lume-On™ illumination lights.
Yes, it is approved to the latest 2010 SOLAS standard and CE ISO12402-2, making it suitable for demanding professional environments like wind farms, superyachts, and oil rigs.
