Smith Optics Airflow Ski Goggles are ready to take on the steepest slopes! The Smith Airflow Series of ski goggles features a double-paned lens. The outer lenses of the Smith Optics Air Flow Goggles have vents in the brow of the goggle lens to increase the circulation of fresh air, keeping the inner lens dry and fog-free. A semi-porous foam filter behind the Smith Air Flow Goggle vents prevents snow and moisture from infiltrating the goggle chamber. Smith Optics protects your eyes and gives you a clear view with a family of snowboarding goggles that can take on anything the ski slopes can dish out.
