Cloudstory PinPoint XXI — Ultra-Precision Optical Titanium Rectangles

The Cloudstory PinPoint XXI is engineered for the wearer who requires both optical perfection and lasting refinement in a classic rectangular titanium frame that performs equally in boardrooms and mountain trails. The 1.4 mm slim rectangular mineral glass lenses are centration-verified to within 0.03 mm of the optical axis — a tolerance reserved for medical-grade optical instruments — ensuring that the visual center aligns precisely with the pupil at the correct vertex distance for zero induced prism. The frame is fabricated from beta-titanium alloy, a formulation with 40% greater elasticity than commercially pure titanium, allowing the temples to flex 15 degrees past the open position during fit adjustment and return exactly to alignment without residual deformation. PVD color options include matte charcoal, brushed platinum, and IP rose gold, each applied over the full frame surface to a uniform 3-micron depth. The nose pads are constructed from liquid silicone rubber over titanium stems, conforming precisely to any nose pad angle and providing a non-slip contact surface even in high-humidity environments. The endpiece construction integrates the hinge barrel directly into the machined frame endpiece rather than welding a separate hinge block — eliminating the weld stress failure point common to less refined titanium frames. Includes a hard-shell titanium tube case. Lens width: 55 mm. Bridge: 17 mm. Temple: 140 mm. Weight: 16 g.
