PRODUCT DESCRIPTION

Experience ultimate alpine exploration, high-performance athletic defense, and technical innovation with this premium luxury sport masterpiece from Oakley. Cultivated as a flagship mountaineering and high-altitude silhouette within the brand's legendary "Sport Performance" design collection, the Clifden (0OO9440) sunglasses feature an understated, stealth-inspired Matte Black finish. Constructed from Oakley's proprietary, ultra-lightweight O Matter™ front framework combined with high-strength injected structural temple arms, this engineered layout serves as an elite style signature for the modern sportsman, delivering an authoritative look that structures and complements oval, heart, and square face shapes flawlessly.

Meticulously engineered to the absolute highest standards of athletic craftsmanship, this full-rim frame successfully merges extreme structural resilience with a perfectly balanced, feather-light feel on the face. Sculpted from premium high-grade O Matter™ and high-performance polymers, it is engineered with a wide frame fitting profile, a high bridge fit geometry, and a classic structural key bridge design to guarantee a custom, slip-free layout and tailored optical alignment under grueling conditions. This tailored medium layout (Size 54) features a commanding, vintage-inspired round mountaineering silhouette that is precisely proportioned with a deep 51.0 mm lens height, a 54.0 mm lens width, a 129.9 mm hinge-to-hinge width, and 146 mm temples for immaculate weight distribution.

The high-performance optics feature Oakley's industry-leading Prizm Black Polarized lenses (Gr001 - Grey Base) constructed from premium, impact-resistant Polycarbonate material. Set on an advanced, distortion-free Base 6 curve with a 54.0 mm effective diameter, these premium lenses offer elite Category 3p sun protection with a highly protective 11% Visible Light Transmission (VLT)—making them perfectly optimized for driving, road use, maritime environments, and intense high-luminosity daytime wear. Engineered with specialized Prizm™ contrast enhancement technology and a specialized multi-layer polarized core, they completely eliminate blinding horizontal reflection and surface glare while heavily boosting color and detail. The lenses are fortified with a factory Solid Mirror coating to repel harsh overhead light. This premium sports layout is also fully progressive friendly, engineered precisely to house custom single-vision or progressive prescription sunglass lenses.
