Notwithstanding the present application of this patent, people who use

this patent do not feel comfortable because of the anti-evaporation pad

that is attached to the upper part of the mask. Also, this pad is not

washable due to the complicated structure of the mask so that is not

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The functions and structure of this invention according to the

drawings is as following.

FIG. 1 is an overview of the invention, FIG. 2 is a detailed

drawing of part A of the invention as shown in FIG. 1, FIG. 3 is a

detailed drawing of part C-C of the invention as shown in FIG. 2,

FIG. 4 is another overview of the invention. FIG. 5 is a section of part

B-B' of the invention as shown in FIG. 4 and FIG. 6 shows the

invention being worn by the user. Reffexing now to FIG. 1 and 3, the invention comprises the body
