Flexible Urethane Frame - Engineered to work in unison with individual facial features, Smith uses a unique urethane compound that maintains its flexibility in extreme cold temperatures. Flexibility of their frames is further enhanced by Smith's Split 'V' nose, allowing the frame to further conform to the face and ensure a tight, consistent seal.
Floating Foam Membrane - Eliminates eyeglass temple pressure.
Cylindrical Carbonic-X Lens - Smith has set the standard in lens performance. Each lens is individually molded to offer optimum scratch and impact resistance, increased visual acuity, and enhanced contrast sensitivity. The inner lens is impregnated with Smith's Anti-Fog lens treatments for increased anti-fog performance. The Carbonic-X lens meets Class 1 optical standards as well as ANSI Z80.3 standards.
Fog-X Lens Treatment - Smith's Fog-X treatment employs a hydrophilic, micro-etched surface to absorb moisture and disperse it over a wide surface area to prevent fogging. Because it is physically carved into the lens, it can't be wiped away like other fog treatments.
