The Line Miner L uses a streamlined frame design and a large cylindrical lens that sits close to the face to create an exceptional field of view. Packed full of features it offers skiers and snowboarders the protection and comfort they need from their goggles to enjoy endless days in the mountains. The frame is a large fit but without feeling oversized. This clean design is the signature model for snowboarder Scotty James, one of the best halfpipe riders around and known for going high.Lens: Prizm Black IridiumVLT: 5.5% (CAT 4)Size: LargeLens Shape: Visual Light Transmission, VLT, refers to the amount of light that penetrates a lens. A low percentage means less light passes through and a higher percentage lets an increased amount of light through. A lens with a lower VLT rating is better for bright conditions, where as one with a higher VLT is more suited for overcast and snowy days.Main LensPrizm Black Iridium is suited to bright light and bluebird days; the Iridium coating reduces glare from sunlight reflecting off the snow, whilst the rose tint increases definition. Prizm technology blocks specific wavelengths of light whilst boosting others to provide maximum contrast and enhanced visibility. This greater clarity results in reduced reaction times and increased performance over a wide range of light conditions.
