How does this fit differently than a standard I/O MAG goggle?

In a traditional goggle, 12-15mm of face foam does most of the work establishing fit by adjusting between the frame and the contours of your face. With I/O MAG Imprint 3D, the frame itself is tailored to your face. This in combination with a much thinner foam, acts to reduce pressure points, as well as light and air leaks, while allowing for lower strap tension.
