Oakley HSTN SQ Casual Sunglasses

Oakley HSTN SQ Casual Sunglasses

The Oakley HSTN SQ is a premium lifestyle sunglass that masterfully redefines the original HSTN attitude by introducing a sharp, squared-off silhouette with dynamic modular color play. Proving that subtle design doesn't have to mean boring, this elevated frame features premium metal structural details that inject a sophisticated, contemporary aesthetic into your daily wardrobe. The lightweight frame is meticulously injection-molded from Oakley’s proprietary O-Matter™ thermoplastic material, engineered to provide significantly greater structural strength, impact resistance, and flexible comfort than traditional acetate. Built to withstand warping or deforming over time, the stealthy Matte Black chassis is outfitted with patented Unobtainium® nose pads that increase their slip-free grip as you perspire to ensure a secure fit. This edition features elite Prizm™ Grey lenses with a 17% light transmission rating and a neutral grey base color. Designed and tested under extreme high-mass and high-velocity conditions, the lenses optimize color contrast, eliminate blinding outdoor glare, and deliver uncompromising impact protection in bright, open sunlight environments.
