Seago 3Dynamic 300N Automatic Harness Life Jacket

The Seago 3Dynamic 300N Life Jacket is Seago’s flagship professional inflatable lifejacket, designed for extreme offshore sailing, commercial marine use, and serious boating enthusiasts. Combining elite safety performance with exceptional all-day comfort, its 3D contour fit design is lightweight, ergonomic, and unobtrusive.

This adult offshore life jacket features Rapid Buckle fastening, a secure D-ring attachment point for a safety tether, and a burst zip system for fast automatic inflation. Once deployed, the advanced S-Design lung technology helps channel water away from the airway, while the integrated spray hood provides added protection in rough conditions.

For maximum reliability, Cylinder Safe technology prevents accidental CO₂ cylinder unscrewing, and a clear status window allows quick visual inspection of the re-arming mechanism. An automatic LED SOS life jacket light activates on contact with water for enhanced visibility. A water-resistant pocket provides convenient storage for a knife or PLB.
