Recently refined for better vapor-clearing performance Smith's Fuse Goggle offers exceptional optic precision in great hand-painted frame styles. This goggle is the smart pick for gear-savvy skiers and snowboarders who want optimal functionality at a modest price. The Fuse Goggle has Smith's Carbonic-X lens an amazingly clear design that meets Class 1 optical standards with TLT Optics. These lenses are individually molded to increase the scratch and impact resistance at all temperatures. Along the top of the lens you'll find a venting system with a switch that you can open and close depending on how fast you're going. This is Smith's successful Regulator venting design. Smith usually recommends keeping the Regulator wide open while stopped or waiting in lift lines but you may need to close it up before starting any high-speed runs or you may shed some tears in the cold air. Another nice touch on the Fuse goggle is Smith's articulating outrigger positioning system. It's an extra hinge that extends from the corner of the frame to help the strap stretch around the contours of your ski or snowboarding helmet. This extension creates an even pressure across your brow and nose instead of that annoying stretch sensation you might feel from goggles that are not compatible with helmets. The big benefit from the articulating outrigger is the fit resulting in a complete seal that potentially keeps your face warmer and far more comfortable.
