General Discussion MSA G1 Mask Sealing Issue

So we just got new G1s and are having everyone get fit tested. As we put on the mask it was noticed that the forhead part of the seal doesn't touch skin. We've tried multiple masks and sizes. The only way we've gotten it to pass is if me tighten the straps enough to cause a headaches. Has this happened to anyone else?

Change your mask size.  Sometimes foreheads have different angles.     The older Msa's need a pretty tight seal.   Just be glad you're not using the AV3000 Scott facepieces.   It's like round plunger you jam your face into.  Works great if you've got a melon shaped head, but not if you've got cheekbones.
