Selectable safety options make the Onyx A/M-24 Auto/Manual Inflatable Life Jacket a must-own for any outdoors and water sports enthusiast. The low-profile design keeps you cool in warm weather and offers less-restrictive range of motion. A combination of 200D nylon ripstop and 200D nylon oxford make up the protective cover, ensuring this vest is tough enough to handle any open-water adventure. D-ring attachments also allow you to bring along tools and other small accessories that don't fit in the pockets. The A/M-24 Vest is convertible from automatic/manual to manual inflation only, meaning you can set your level of safety depending on the situation. Automatic inflation is more beneficial with rough-water use, while manual inflation is better-suited for activities on calmer waters like fishing or canoeing.
