Oakley's 2018 R3 collection sees the introduction of the Chamber. An Rx frame that is inspired by the Field Jacket. The Performance Sunglasses released in 2018. Oakley describe them as similar to the Pitchman and brother to the Cartridge. The new frame brings a new, never seen before design. This is the first Oakley product to feature the new Hollowpoint Hinge. The new design removes the outer casing which usually featured the Oakley icon and exposes the mechanism. The frame is Oakley's O Matter material merged with Titanium Temples.
