CB.01 bio-based sports sunglasses
Two brands, one mission
The CB.01 is the result of a shared vision: sustainability without compromise. ATTAAC and BOLDWILL came together with a single mission — to challenge the status quo of sports eyewear.
The outcome is a bold new standard for athletes: sunglasses that are high-performing, durable, and created with respect for the planet .
European craftsmanship
Every detail of the CB.01 speaks to thoughtful, European-made quality:
- Frame — Made from 100% bio-based material derived from castor beans.
- Lenses — Equipped with premium ZEISS® optics with advanced coatings for clarity and scratch resistance. Made of 39% biomass from wood and agricultural waste, and 61% fossil-based mass.
- 3D Printed — Frames are 3D printed and assembled by hand in Europe, reducing waste and ensuring precision.
- Accessories — Each pair comes with a custom protective pouch and cleaning cloth made from 54% TENCEL™ Lyocell and 46% TENCEL™ Modal. Three different-sized skin-friendly, hydrophilic silicone nose pads are also included for a guaranteed perfect fit.
By combining craft, technology, and responsible sourcing, CB.01 delivers a product that is as sustainable as it is high-performing .
Performance by nature
The CB.01 isn’t just eco-friendly—it’s a serious piece of performance gear. The concrete grey edition pairs lightweight bio-based frames with premium ZEISS® lenses engineered for optical precision, durability, and UV protection. Athletes can count on structural stability, clarity, and comfort, whether on long rides, runs, or alpine climbs .
Road to 100% bio-based
At present, no performance sunglasses can be made entirely bio-based without compromising function. But with CB.01, we’ve come as close as possible: the frame is fully plant-based, while the lenses already incorporate bio-based inputs from agricultural waste. Together, ATTAAC and BOLDWILL are pushing toward the 100% bio-based goal—a milestone we believe is within reach in the coming years .
Why it matters
Eyewear is more than a detail of an outfit—it’s an essential tool for performance and safety. But it also tells a story. With CB.01, every ride, every run, and every climb becomes part of a larger mission: to prove that sport and sustainability can be seamlessly united.
