The U.S. Navy MK-1 Inflatable Life Vest is designed for rescue professionals, naval aviators, and emergency response crews who operate in high-risk environments. With a durable, fire-retardant shell made from cotton and high-tenacity nylon twill, this vest is built to withstand the toughest conditions while providing essential flotation and safety features.
Designed with functionality in mind, the MK-1 includes easy-access hook-and-loop pockets and a shoulder patch, allowing users to store lifesaving tools like a whistle, strobe light, and dye marker when needed. The adjustable back harness ensures a secure and comfortable fit, even when worn over standard fall protection gear. Reflective patches enhance visibility in low-light conditions, helping crews locate personnel faster in critical situations.
The vest inflates instantly with a pull of the inflation cord or manually via an oral tube, providing reliable buoyancy when it matters most. Whether used in military operations, aviation, or maritime rescue, the MK-1 is trusted for its durability, practicality, and life-saving reliability.
Note: Additional rescue tools can be stored within the vest but are not required for its primary flotation function.
