MOSLEY TRIBES GATES RED AUTHENTIC SUNGLASSES FRAMES 50-22 | eBay。The Mosley Tribes Gates sunglasses are a highly sought-after, rare model from the urban-focused sister brand of Oliver Peoples. Known for their distinctive style, select limited editions of this specific model featured a unique mechanical flip-up lens design, allowing wearers to seamlessly transition between indoor and outdoor environments. The \"Flip-Up\" Mechanism: The most recognizable trait of the Gates frame is its unique mechanical folding design. They feature flip-up sunglass lenses built over a secondary rim. This functionality makes them popular for retro fashion styling and convenient for retrofitting with optical prescription lenses beneath the sun tint. Frame Silhouette: They utilize a classic, medium-sized \"Wayframe\" silhouette (a sporty adaptation of the traditional Wayfarer shape). Standard Measurements: Frame size of 50▢22-145 (50mm lens width, 22mm bridge width, and 145mm temple length). Optics: Outfitted with premium high-utility lenses featuring an internal anti-reflective coating to prevent glare. Never used. New without tags. Comes with generic red case.
