The Smith I/O 7 Snow Goggles With Blackout And Red Sensor Lenses are the massive cylindrical lens of the redesigned Squad made from molded carbonic-x material so it’s tough, but still has Fog-X technology and TLT Optics for crystal clear vision. The minimal semi-rimless frame technology and newly designed, fully integrated strap connection point delivers the function you need without extra moving parts. Fun on the hill with your friends is amplified when you don’t have to worry about whether or not your gear is dialed. The Blackout Lens has 10% Visible Light Transmission. Dark gray base lens tint cuts glare and reduces eye fatigue in bright, sunny conditions. The Red Sensor Lens has 55% Visible Light Transmission. Light rose base lens tint with a multi-layer red sensor mirror maximizes color definition and increases depth perception in varying levels of flat light conditions.
