When it comes to navigating through tight trees or steep lines with complete and utter lawlessness (for the most part) rely on the Spy Marshall Goggle with Happy Lens to help lead the way. Designed with a medium-to-large silhouette the Marshall features a pliable Flex Frame for a pressure-free fit while the Isotron Face Foam boasts a moisture-wicking fleece for dry comfort when the going gets rough. Additionally the Marshall is constructed with a helmet-friendly siliconized strap that ensures the goggle stay put when cruising through bumpy terrain. However the true genius of the Marshall lay in its Happy Lens technology. Not only does the Happy Lens enhance color and contrast but it also filters out short blue-wave rays ultimately reducing eye fatigue for a more laid-back reliable line of vision.
