A large and close fitting frame with an extra large lens, the Smith Syncline gives almost the full coverage and protection of a set of googles, while allowing far more airflow than any goggle can possibly provide.
An integrated top bumper makes sure that no matter how tough the trail, there's no helmet rattle. Adjustable nose pads further fine tune the fit and Megol grippers at the temples keep things secure even when the going gets rough.
The high contrast mirror lens helps to define detail in dull or dappled light, picking out trail features the eye might otherwise miss. They also include a spare clear lens for the dark and muddy days, when all you need from your eyewear is protection from mud and trail debris.
