The original Line Miner mask was created with the goal of providing the best peripheral vision, with a cylindrical-style design. We expanded the range to create a complete lineup, adding to the arsenal this youth-sized mask equipped with Oakley's industry-leading Prizm lens technology. This narrower frame offers increased visibility and better helmet compatibility, an enlarged lens surface for optimized peripheral vision, and a 35mm-wide adjustable strap. The strap attachment plates provide comfort and support, and discreet notches under the strap attachments ensure compatibility with most prescription lens inserts.
