New Fast Metal Blue Speed Demon Flash Beryllium Polarized Lens Eyewear
Machined and formed from 7075 aircraft grade aluminum using family known proprietary manufacturing technique. The Speed Demon and Pioneer are both 9 base wrap around lens and frame designs. Fast Metal uses 9 base lens technologies due to the 30 degree rake/wrap on the frame. Other brands bend the frame to 30 degrees but dont use a 9 base lens.
