Designed and developed to offer incredible comfort and performance, the Hero Goggle will exceed your expectations. Every detail has been refined for optimum performance and best fit. Innovative features like Thor's drilled frame, which increases air circulation to prevent fogging, and Thor's molded outrigger positioning system ensuring a secure fit make the Hero Goggle a leader in performance eyewear. All this technology wouldn't be beneficial if the lens wasn't perfect. That's why every Hero Goggle comes standard with an optically correct, mirrored smoke Lexan® lens with anti-fog coating and UV protection. Included is an additional clear lens with every pair as well as a soft, supple goggle bag to keep everything clean. Tear-offs are also available and mount easily since all Hero lenses come standard with mounting pins.
