Oakley Flak S

The Oakley Flak (X)S is a pair of sports glasses specifically designed for youngsters and people with narrow heads. These glasses share the same features as the Flak 2.0 series. The frame of the Oakley Flak XS is made from O-Matter material. This material is very strong, flexible, and yet very lightweight. The earsocks and nosepiece are made from Unobtainium, which ensures the glasses stay in place even when perspiring or at high speeds.
