1. Intelligent inflatable lifesaving function: When the human body falls into the water, the lifesaving system will automatically start in 5S to inflate the airbag and provide buoyancy.

2. Automatic turnover function: When the human body falls into the water, it will automatically turn over and straighten within 2 seconds, so that the human body can float on its back on the water surface, with its face facing the sky 100mm above the water surface, and a safe floating state with a backward angle of 20-50 degrees.

3. Manual system compatibility: automatic and manual dual start mode, pull the start rope on both sides to start the airbag manually.

4. The effective time of buoyancy is more than 48 hours: after 24 hours, the loss rate of buoyancy is less than 5%, and it can maintain a safe floating state for more than 48 hours.

5. Weatherproof: The coat has the function of windproof and rainproof, and the lifesaving system is stored inside, which is beautiful and convenient to use.
