The ‘Ultimate Driving’ Sunglasses unite the racing heritage of Team Ikuzawa with the exceptional craftsmanship of Japanese eyewear atelier Native Sons. 

Native Sons, founded by eyewear industry veteran, Tommy O’Gara, the frames are designed and manufactured by hand by a small team of expert craftsmen in Sabae and Fukui City Japan. Frames are constructed using custom Takiron cotton based acetates, high grade titanium plated with custom gold and silver formulas, and Shima Optics lenses are used exclusively.

From the frame geometry to the lens performance, the design features straight temples for ease of wear with a helmet. 

The frames are named ‘Tetsu’ in tribute to Tetsu Ikuzawa.
