Mustang Survival's first inflatable lifejacket is now available. The MD3157 is the first inflatable approved and certified as a lifejacket by Transport Canada and was designed for use in severe marine environments. The MD3157 was designed to self-right a faced-down person in seconds and provide increased in-water visibility. It also features a lightweight design and advanced inflation technology, designed to provide the wearer with improved mobility and comfort. The ability to maneuver quickly and freely is especially critical to those users who provide assistance during emergency situations. The MD3157’s compact design also makes for easier storage and accessibility on vessels where carriage of a lifejacket is required. • Hydrostatic Inflation Technology (HIT™).
