You have to take notice when Electric says the Tech One Pro Sunglasses might be the comfiest pair of sunglasses it's ever made. These sporty sunnies style a half-frame design for a lighter feel, and the discrete nose pads hug your nose for a stay-put fit. Electric coated the lenses to resist water stains, oil smudges, and unwanted reflections. The lenses are polarized to deflect glares off water and windows.
