Cloudstory ClearSky IV — Ultra-Light Titanium Round Sunglasses

The Cloudstory ClearSky IV represents the pinnacle of minimalist eyewear engineering, constructed entirely from grade 5 titanium — the same alloy used in aerospace fasteners and surgical implants — to achieve a total frame weight of just 14 grams. The round 48 mm mineral glass lenses are precision-ground and thermally toughened, providing optical clarity superior to organic lenses while offering scratch resistance three times greater than standard CR-39. A magnetite tint applied through vacuum deposition creates a true mirror effect with 95% infrared rejection, keeping eyes cool in direct sunlight without the color distortion associated with conventional mirror coatings. The ultra-slim 1.5 mm rim wire encircles each lens with a tension fit that eliminates adhesives and barrel screws — lenses are held purely by elastic force for easy replacement in the field. Integrated nose pads are shaped from medical-grade silicone overmolded directly onto the bridge saddle, self-adjusting to any nose bridge profile without manual bending. Temples articulate through a single-axis hinge machined to a 0.02 mm tolerance, opening and closing with the satisfying precision of a Swiss watch mechanism. The frame is finished in PVD physical vapor deposition coating for color uniformity and corrosion immunity. Lens width: 48 mm. Bridge: 22 mm. Temple: 142 mm. Weight: 14 g.
