The RSCY-A4 Offshore Life Jacket is a SOLAS-standard marine safety vest designed for adult use on sea-going vessels, offshore platforms, and other maritime environments. It delivers at least 150 N of buoyancy to help keep wearers afloat and their heads above water in emergencies. Constructed with bright, high-visibility polyester Oxford fabric and SOLAS-grade reflective tape, it enhances visibility for rescuers in low-light conditions. A built-in rescue line, whistle, and life-jacket light improve safety and help signal for help when needed. Adjustable belts and a universal fit accommodate adults weighing from ~43 kg up to ~140 kg and height above ~155 cm. The EPE foam core is water-resistant and maintains buoyancy even after prolonged exposure. Certified by CCS and EC to meet international life-saving equipment standards, it’s reliable for offshore and coastal work or travel. Overall, this life jacket balances comfort, high visibility, and essential safety features for serious marine use.
