There's little about the Oakley Half Jacket that hasn't already been said by its overwhelmingly appreciative wearers, or impressive sales numbers since its release way back in 2002. The new Half Jacket 2. 0 XL continues the longstanding traditions of Oakley's first interchangeable dual lens sport performance sunglass, with a slightly updated revision of the half-rimmed classic. The 2. 0 redesign takes width and fit cues from its predecessor, while widening out the sculpted earstems and using a more confident set of integrated hinges. In essence, the 2. 0 blends the best aspects of the initial Half Jacket, and Oakley's more recent Fast Jacket, but without the Switchlock technology. Like every Oakley design that leaves their Foothill Ranch factory, the Half Jacket 2. 0 XL not only meets, but exceeds the rigorous standards set by the American National Standards Institute (ANSI). Granted, the worst that most of us will ever see is the occasional tree branch, or fast-flying insect, but Oakley still designs their lenses to withstand impacts as great as these, keeping your eyes protected wherever you ride. What good would safety standards be without near-perfect clarity? Oakley's patented High Definition Optics (HDO) boasts some of the best clarity in the industry. These optically-correct lenses are constructed from pure Plutonite, Oakley's proprietary polycarbonate that not only blocks all harmful UV-A, UV-B, UV-C, and harmful blue light up to 400nm, but is also the heart of the impact resistance of which Oakley so proud. Each lens is finished with a hydrophobic treatment that repels moisture buildup from water or sweat, and contaminants like fingerprints or smudges from sunscreen. The Half Jacket 2. 0 XL is constructed from a super-lightweight O-Matter polycarbonate frame, and is available in two color options: Polished Black with Black Iridium lenses, or the traffic cone-inspired Blood Orange with Fire Iridium lenses. Oakley's Iridium treated lenses pull double-duty:.
