The Fox Airspace Mirer Bike Goggles offer the best-in-class viewport for unparalleled peripheral vision. These goggles are built with a three-layer face foam with a fleece Liner that provides superior sweat absorption while their 45 mm non-slip silicone strap improves grip on the helmet. They feature a Variable Lens System (VLS) that allows transfer of standard and injection molded lens, while their six-pin lens retention system keeps the lens securely attached to the frame and include a Lexan™ lens that offers UV protection plus an additional clear lens. Their outrigger design creates a secure fit to keep dust and debris out of the viewport. Get the best vision, comfort and performance with the Fox Airspace Mirer Bike Goggles!
