The Smith Reason OTG goggles are built for skiers and riders who rely on prescription eyewear and refuse to sacrifice clarity, comfort, or helmet integration. Designed specifically to fit over-the-glasses (OTG), they create a pressure-free environment that lets your eyewear sit naturally—no pinching, no hot spots, no distractions—just clear vision that lasts all day.

Smith’s Optical Docking System (ODS) adds another layer of versatility, allowing you to use a prescription lens insert for a streamlined, glasses-free setup if you prefer. Either way, the Reason OTG is engineered to keep airflow moving and fog at bay, even when paired with a helmet and worn hard from first chair to last run.

A cylindrical Carbonic-x lens delivers dependable clarity and impact resistance, while built-in Airflow technology and a Fog-X anti-fog inner lens work together to regulate moisture and maintain a consistently clear view. The result is reliable optics in changing conditions, without the constant need to stop and clear your lens.

Comfort comes from thoughtful design details. A floating foam membrane eliminates pressure from eyeglass temples, and two-layer DriWix face foam manages moisture while sealing softly against the face. Sized for larger face shapes and fully compatible with Smith helmets, the Reason OTG offers a balanced, all-day fit that simply works.
