After compression and 3D three-dimensional molding, its thickness is about 4 cm (the domestically produced 5-6 pieces of thin hair material are about 5-7 cm thick). Life jackets produced in accordance with standard specifications have their buoyancy standards: generally 7.5 kg/24 hours for adults and 5 kg/24 hours for children, so as to ensure that the chest is above the water surface. The bright colors or the colors with fluorescent components in the life jacket can stimulate the optic nerve. It may be related to the wavelength of this color, which is easily accepted by human eyes and not easily confused by other colors. This will be more conspicuous.
