PURPOSE:To fulfill a function sufficiently even if one might be shot or attacked with a sharp pointed arm or fallen into the sea by housing a pair of bag bodies having independent air chambers, inside a jacket formed with a bulletproof material, and providing a sheet made of a bulletproof material on its front side. CONSTITUTION:Even if a crew-member in a jacket might be shot under an emergency condition, since the jacket 1 itself on the outside and the front sides of bag bodies 30, 31 which are housed inside are formed with a bulletproof material, the crew-member can be protected by these parts. Furthermore, since the air chambers 40, 41 of the bag bodies 30, 31 are not broken, even if the crew-member might fall into the sea afterward, a cut case is normally operated due to the infiltration of seawater, to inflate the air chambers 40, 41, which function as a life vest. Also, even if the crew-member might be shot or pricked with a sharp pointed arm after fallen into the sea, he can float safely since the air chambers 40, 41 are not broken.
