Half Sunglasses - It was only a matter of time. We’ve been perfecting open-edge lens architecture for years, giving athletes like runners and cyclists a full field of vision with no frame rim to block downward view. In a completely separate lab, our metallurgists were toying with 425,000 watts of plasma lightning to shape X Metal , an ultra-lightweight titanium alloy. Somehow the performance fanatics and the metal heads got together and spawned a design that mixes art and science so completely, you can’t tell where one ends and the other begins. This is what happens when our athletes and engineers are allowed to mingle without an adequate supply of paint balls. Here’s where it goes over the top: The lenses are optimized with Oakley Hydrophobic coating, a permanent shield against water sheens and a smudge-resistant barrier against skin oils and lotions. That means the unbeatable clarity of High Definition Optics (HDO ) stays razor sharp and clear, and with lens contours that maximize peripheral view, it’s a performance advantage that borders on unfair. You also get the industrial-level impact resistance and 100% UV filtering of pure Plutonite lenses, plus optional IRIDIUM lens coatings that reduce glare and balance light transmission. The Half X sunglasses have a lightweight all-metal frame that stays in place with a Three-Point Fit that takes advantage of supple Unobtainium components, specially formulated to increase grip with sweat. Custom-engineered spring hinges add even more comfort. Oakley X-Metal : the only 3-D sculpted, hypoallergenic, all metal frame on earth. Lightweight Titanium alloy with phenomenal strength-to-weight ratio and rugged durability Custom engineered spring hinge mechanisms for added comfort Comes standard with Oakley Hydrophobic/Oleophobic anti-smudge lens coating on all lens options Optimized peripheral vision and side protection of 8.75 base lens curvature Comfort and performance of Three-Point Fit that holds lenses in precise optical alignment Optical precision and performance that meets ANSI Z87.1 standards Impact resistance that meets ANSI Z87.1 Basic impact standards UV protection of Plutonite lens material that filters out 100% of UVA/UVB/UVC & harmful blue light up to 400nm Glare reduction and tuned light transmission of Iridium lens coating Patented hydrophilic Unobtanium earsocks ensure a snug, secure fit Includes X-Metal Collector’s Edition Coin Also available in: Custom, Polarized, Replacement Lenses
