The Hooligan is sleek and stylish eyewear with photochromic lenses, so they can go with you in all lighting condition. The frame wrap around the face and has a slight cup on the edges of the frame to minimize wind disruptions without the need for foam. The lenses are photochromic starting with a light tint (85% transmission) and transform to a medium grey (25% transmission) in bright light. The Hooligan also comes with a microfiber pouch for easy transport. *Please note that while these glasses would presumably pass ANSI Z87.1-2010 standards, they are NOT certified, and are therefore not endorsed as safety eyewear by Safety Glasses USA.
