The cylindrical lens of the Squad is made from molded carbonic-x material so it's tough, and still has Fog-X technology and TLT optics for crystal clear vision. The minimal, semi-rimless frame technology and fully integrated strap connection point deliver the function you need without extra moving parts. Fun on the hill with your friends is amplified when you don't have to worry about whether or not your gear is dialed.
