Introducing the new Oakley Mainlink sunglasses. The inspiration for the frame comes from the popular Oakley Crosslink. The stylish frame is made of durable but light O Matter. The frame has a secure fit, guaranteed by the Unobtainium® earsocks and nosepads which increase their grip when you perspire. It is the perfect sunglasses for an active lifestyle. Oakleys patented Three-Point Fit increases comfort and keeps the lenses in optical alignment. The UV400 lenses also offer unrivalled impact resistance.
