Abstract: A scuba mask structure includes at least one window section, a mounting seat for receiving an attachable device to removably attach thereto, and an integrally formed supporting section. The supporting section is insert molded around a periphery of the window section and an end of the mounting seat so that the mounting seat is at one side of the supporting section and the window section is at another side of the supporting section so as to form a seamless scuba mask. Such a structure is formed by first placing the window section and the mounting seat in a mold and forming through injection the support section to be insert molded with the mounting seat and the window section for wrapping around a periphery of the window section so that a seamless scuba mask that, in the entirety thereof, has an integrally formed configuration.
