The Onyx A/M-24 Inflatable Adult Life Jacket provides essential features for water safety. It can convert to manual-only inflation mode via a pull-cord and oral inflator tube. A clear viewing window indicates if the vest is armed and ready with green for armed and red for re-arm. It offers all-day comfort with its low-profile lightweight construction and plush extended neoprene neckline. Repacking is made simpler with the Quickburst zipper which connects to the life jacket to prevent snagging. The outer cover's durable nylon Oxford fabric prevents tearing and punctures and reflective material enhances visibility.
