In skiing and snowboarding, the Fall Line range refers to the line along a mountain, i.e. the slope. Inspired by Line Miner and the wide field of vision of a contourless goggle, Fall Line M joins Oakley's “LINE SERIES” of cylindrically styled snow goggles. Suitable for medium-sized faces, Fall Line M is optimized to suit many face types and is designed to be compatible with most helmets. The goggles feature Oakley's Ridgelock technology, lenses that can be changed quickly and easily, and a full seal to prevent water from getting inside.
