The Smith I/OS Goggles have a small/medium fit and fit smaller than the Smith I/O Goggles.

The Carbonic-X spherical outer lens is individually molded to offer optimum scratch and impact resistance, increased visual acuity and enhanced contrast sensitivity, while the inner lens is impregnated with Smith’s Fog-X treatment for increased anti-fog performance, and 100% visual accuracy thanks to TLT (Tapered Lens Technology) optics. These goggles also come with two performance mirror lenses that, like all Smith lenses, provide 100% protection from UV rays.

Smith’s patented Vaporator lens technology means the lenses are robotically cut and bonded together with an airtight silicone bead to eliminate lens delamination (the number one cause of between-the-lens fogging). The micro-porous Porex™ filter completes the system: the world’s strongest thermal lens barrier, this filter is structured so air molecules may pass through while water molecules can’t, making it easily able to adjust to varying altitudes.

The Smith I/O Goggles feature an ultra-wide, silicon backed strap with a QuickFit Strap Adjustment system complete with a clip buckle.

The dual layer DriWix face foam is ultra-lush and a perfect fit. The compression-molded face foams seal out the wind and moisture for maximum comfort and performance.
