Right from the start, the browless frame has been a unique design feature of the glasses. The browless frame helps vent the SlingShot and reduce glasses fogging.

I like this design feature since I have been on the receiving end of a fogged eye pro during a stress shoot, resulting in my inability to shoot while wearing shooting glasses with a brow frame after running in humid weather. Features
