PROBLEM TO BE SOLVED: To prevent the deterioration or breakage to enhance the durability by providing a takeout port capable of housing and taking out a buoyancy material on a facing material, dividing the buoyancy material into a plurality of pieces of a form passable through the takeout port, so that the buoyancy material can be taken out through the takeout port to wash or dry the facing material inside or the buoyancy material. SOLUTION: A housing space for housing a buoyancy material 2 is formed in the inner part of a facing material 1. The housing space communicates with all sides of a vest form. A takeout port 5 for housing and taking out the buoyancy material 2 is linearly provided on the body contact surface side of the back side lower end of the vest form of the facing material 1. A fastener 6 is peeled to open the takeout port 5, whereby the buoyancy material 2 is housed and taken out. The buoyancy material 2 consists of six pieces with different forms of a front right upper half part 21, a front left upper half part 23, a front right lower half part 22, a front left lower half part 24, a rear upper half part 25, and a rear lower half part 26. Since the buoyancy material 2 can be taken out through the takeout port 5, and washed and dried, the deterioration and breakage of the buoyancy material 2 can be prevented. |
