Joe, you say the mask is too tight,so the back needs to be slit for you to get it on.What I,m thinking is, that should you instate a zipper, surely when you fasten it it still will be tight, thus putting stress on the area the zipper is adhered to.Have you considered punching holes either side of the slit, then add eyelets, then simply lace it up.That way you can tighten it up just right without overstretching your mask :yes:
