The Smith Knowledge OTG Turbo Fan Goggles have a large fit and are O.D.S. and eyeglass compatible.

The Carbonic-X 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.

Turn on the patented micro-electronic fan in the Turbo Fan Series and in the low setting, the Turbo Fan system will run continuously all day long (up to 50 hours on one AAA battery) to exhaust moisture in the goggle, and the high setting can be used to quickly exhaust moisture in extreme conditions. 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 Knowledge OTG Turbo Fan Goggles feature an ultra-wide, silicon backed strap with a QuickFit Strap Adjustment system complete with a clip buckle and an articulating strap positioning system for the ultimate fit.

This product may contain chemicals known to the State of California to cause cancer, or birth defects, or other reproductive harm.

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, and the floating foam membrane eliminates eyeglass temple pressure.
