ROLF EYEWEAR Evolved Collection is made of hand-picked wood. Each pair of glasses is unique in color and grain and is purely plant-based material and combines high wearing comfort with stability and lightness. Colourful nuances meet deep black and give the frame a special depth. The patented Flexlock® joint ensures flexibility and durability. A broader palette of rare species. Smoked Larch with its caramel-brown tone, Steamed Robinia from Europe, Tineo from Patagonia. Includes the Twisted sub-line, where veneers are rotated 90° for grain patterns that never repeat. No two pieces of wood or stone are identical. Which means no two Rolf frames are identical either. Every Rolf frame closes with the patented Flexlock® hinge. No screws. No soldering. No metal. The entire frame, including the hinge, is made of natural material.
