Oakley® taps into its surfing heritage with hydra, a razor blades-inspired, semi-rimless sunglass with a shield lens. Featuring the oakley b1b logo on the temples, hydra is accentuated by a modern trigger stem design, reminiscent of razor blades' origins in surf culture. A plant-based bio-matter®* frame and three-point fit helps provide balanced fit and comfort while prizm™ lens technology enhances color and contrast. *bio-matter is made from bio-materials having at least 56% bio-based carbon content (representing ratio of castor oil to fossil sources) Oakley Men's Hydra Sunglasses
