Diablo technology:

Grilimid:
Spy uses flexible Grilamid in its Scoop series and other sport-friendly styles. Grilamid frames are shatter-resistant, comfortable, and ready to take on the world in any climate condition.

Scoop Venting System:
Spy Optic's patented Scoop venting system reduces lens fogging by channeling air behind the lens. Scoop routes air through strategically placed vents of varying aperture on the frame, effectively shutting down fog and keeping your vision clear.

Base Curvature:
8-Significant wrap-around coverage
Spy's spherical sunglasses are available in 4-, 6-, 8-, or 9-Base. Base curve refers to the amount of "wrap" that a lens has, which in turn affects the curvature of the frame. A flatter lens-such as a 6-Base will create a much flatter, squared frame shape, whereas a higher base number will cause a sleek, wraparound fit.

Lens Curvature:
Spy Optic's ARC (Accurate Radius Curvature) lenses are used in to provide the highest quality and most optically correct, distortion-free vision. ARC lenses have an asymmetrical curvature, eliminating lens distortion and providing increased visual acuity.
