The secret to speed lies in minimal air resistance and maximum style. What, you weren't expecting style to be important? The Speedtuck polarized shades from Von Zipper come complete with Tri-Motion optics and the RGNS System for a secure fit at mach speed. That pretty much covers the bases when it comes to aerodynamics, and steez appeal for that matter.
