An elastic headband and a layer of foam padding is all that most goggles use to ensure they fit. But Scott's new Off-Grid snow specs actually allow you to tweak the shape of the frame, so they sit comfy on almost any face.
The company's Fit System uses a set of dials on the underside of the goggles that can be turned with a screwdriver, or a dime, if you don't carry stab-capable tools while on the slopes. Turning the dials to one of four positions changes the curve of the goggle's frame, so that even if you have a particularly wide or narrow head, they should sit comfortably against your face.
