Ski Goggles
Goggles matter more in racing than in free skiing, because a racer is reading terrain at speed in light that changes between inspection and the second run.
The lens does most of the work. Low-light and flat-light lenses lift contrast on grey days and in shadowed courses, which is when most gates get missed. Dark lenses are for bright spring days. Owning two lenses for one frame is cheaper and faster than owning two goggles.
Fit is the other half. A goggle must sit flush against the helmet with no gap at the forehead — a gap lets cold air in and usually means the frame is the wrong shape for that helmet, not that the strap needs tightening.
Shop POC goggles, Sweet Protection goggles and replacement lenses. Goggle and helmet shapes have to agree, so try the two together before race day.
