The Atomic Savor Big FDL HD lens is for our Savor Big goggles, and is super easy to switch when conditions change. The cylindrical lens brings you the unique double-act of HD and Fusion Double Lens (FDL) Technology - giving you high-definition snow contrast and insane clarity without reflections or refractions. As the double lens is laminated together, FDL also delivers a truly epic field of vision that’s up to 20% wider, with the frame virtually invisible when your goggles are on. HD lenses perform in a wide range of light conditions but because of its dark mirror, this silver HD lens is recommended for bright sunny winter days.Features:- Cylindrical Fusion Double Lens (FDL)- HD Lens Technology- 8x Anti-fog Inner Lens (AC)- Stereo Lens Technology- Supreme Anti-scratch Outer Lens (PC)- Hydrophobic Lens Coating
