Self-inflating life jacket

A self-inflating jacket is considered as the most comfortable type of life jacket, since it more closely reminds a harness when put on, but acts as survival equipment when in water. The self-inflating jacket has a small compressed air canister inside which will fill the jacket with air in water. There are two main types of self-inflating jackets: with some, a person needs to manually trigger the inflation by pulling a cord, others inflate automatically while in water. Although a self-inflating jacket also offers good movement, it is not suitable for sports where falling into the water in inevitable – re-packing an already inflated jacket is troublesome and takes time.
