The Oakley Flak Jacket 2.0 is slightly larger than that of the Half Jacket and encompasses performance, protection and comfort at the heart of its design. The lightweight O Matter frame material and semi rimless design provides superior comfort and an extensive downwards view. The Unobtaniam ear-socks and nose pads give unrivaled grip to keep the frame secure even when you are dripping in sweat! The High Definition Optic lenses keep vision sharp and precise to the full extent of the wrap and the impact resistance gives you uncompromising protection. The Oakley Plutonite lens filters out 100% of UVA, UVB, UVC and with interchangeable lens technology you can simply swap out the lenses according to the changing light conditions. This classic black wrapped frame with black iridium polarised lenses will give you glare free vision providing the perfect combination for any sporting event. This authentic Oakley frame comes complete with a hard case, soft pouch and a two year warranty.
