Oakley has 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, 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 cant tell where one ends and the other begins. Heres where it goes over the top: The lenses are optimized with 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, its 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 Three-Point Fit takes advantage of supple Unobtainium components, specially formulated to increase grip with sweat. Custom-engineered spring hinges add even more comfort.
