The journey began with titanium—unyielding in strength, yet astonishingly light. What began as a 22-gram frame was distilled, gram by gram, into a 10-gram skeleton that marries durability with weightlessness. For both brands this process was instinctive—an unwavering commitment to performance, where every element is tested, refined, and redefined. Thousands of kilometres logged shaped the frame’s contours, the flex of the temples, the fit. The goal was clear: to create a frame so intuitively functional, it disappears in use.

Cirrus exemplifies pure performance. The titanium frame contours to the face, while flexible beta titanium temples and crosshatched nose pads provide a pressure-free fit. A custom ZEISS shield lens offers maximum coverage, full UV protection, and a RiPel™ coating that repels scratches, smudges, and moisture.

The result: clarity in motion, effortless comfort, and a sense of freedom that keeps the runner focused only on their stride—whether in the quiet rhythm of an easy run or the relentless drive of long-distance racing.

What makes Cirrus remarkable is the collaboration behind it. Cubitts, experts in precision optics, and SOAR, specialists in athletic performance, merging their expertise to create something neither could have conceived alone. The result is a product that feels both inevitable and original—a seamless fusion of two disciplines that surpasses the sum of its parts.

Cirrus is a quiet triumph of restraint and refinement. Stripped back to its purest form, it serves only what is necessary, shedding everything superfluous. At just 10 grams, they are the lightest running sunglasses on the market. After two and a half years of testing, Tim Soar knew they were ready only when, on a two-hour run, he forgot he was wearing them—only reflecting on their effortless performance once the miles were done.
