The all new Flux goggles features a low profile frame and anti-fog photochromic lenses which darken in the sunlight. Dual layer neoprene and open cell foam create a durable yet effective seal to keep wind and debris from affecting your vision. The photochromic lenses start out almost clear (V.L.T. 85%) and go to a light smoked (V.L.T. 32%) while in bright sunlight. The Flux also comes with a microfiber pouch for easy cleaning and transport.
