Ok 3 different helmets and nothing in the manual. What is the little button for that is on both sides just behind the face opening? I thought they were a magnet for attaching some sort of goggle strap but I guess that's not it after searching mounting systems. Also what does everyone use for quick connect mounting systems? I have seen them in use and it looks like u can adjust them so they do not make the goggle fit so tight to the face unlike the strap they come with
