I was checking out a Tech Site
for the I3 goggle system, and it said this.
ADJUSTABLE FACE MASK
The Invision3 features an industry first adjustable face mask. Utilizing two adjustment holes in the frame, you can custom fit your I3 for a loose or closer profile to your face. In today’s game, half an inch can make all the difference in the world.
I don't see anything in the manual about adjusting the mask, and I don't see any holes in the frame that would appear to adjust the mask fit. Can anybody tell me how to adjust the fit of the mask frame to the face?
