Smith Ski Goggles 4D Mag XL 0JX OQ Black ChromaPop Photochromic Red Mirror & CP Storm Blue Sensor Mirror give you the widest field of view yet, at 13% larger than the original 4D MAG. The BirdsEye Vision lens and ChromaPop technology enhance contrast and clarity so you can read terrain changes confidently, while the XL frame provides a spacious, comfortable fit with OTG compatibility for glasses wearers. The MAG lens-change system uses secure magnets for fast, easy swaps when conditions shift, and the 5X anti-fog inner lens, AirEvac ventilation and moisture-wicking three-layer DriWix face foam help maintain a clear and fog-free view. The ultra-wide silicone-backed strap stays firmly in place and integrates seamlessly with Smith helmets for balanced airflow and all-day comfort. Offering 100% UVA/UVB protection, these come with two lenses, a protective hardcase, and a microfiber goggle bag with a spare lens sleeve.
